Ireland in Four Days (and Five Years). Day 3. On to Wicklow.

It’s Day 3 of my final roadtrip, in southeast Ireland.  Check out my earlier blogs as to how I got to Boris Carlow;  that just rolls off the tongue so beautifully I just have to keep repeating it. Boris Carlow.  By rights I should go home.  The forecast is not good, but I want to visit a nearby dolmen and the castle at Carlow and I’ve decided after that to head on to Avoca in Wicklow to see the old copper mines.  The sun was trying to break through so I hit the road at 9am.

It was only 30km to the Brownshill Dolmen, which lies only 4km east of Carlow town  There are over 1,000 dolmens in Ireland but this one is right up there with the best.  It is located in the middle of a large field (by Irish standards) and you know you are dealing with something unusual when  you can see it 400m away poking up over a 2m high crop  of ‘field beans’ (a fodder crop I had never seen before).

Brownshill Dolmen, visible over a crop of field beans.

What makes this one unusual is the size of the granite capstone; it is approximately 5 x 6 x 2 m.  Estimates of its weight vary, so let’s sort this out once and for all.  Volume, based on the above estimate, is 60 cubic metres.  Using a specific gravity of 2.7 (average for granite) and the formula

Tonnage = Volume x SG

we get a tonnage of 162 tonnes.  So that’s my guess, which happens to be greater than the estimates I have read, which range between 100 and 150 tonnes.

Front view of Brownshill Dolmen, showing its massive size compared with the two portal stones and the gatestone.

That is monstrous and certainly the largest in Ireland.  It is a portal tomb dating from 3,000BC.  The front sits on two vertical standing stones (portal stones) and between them is a gatestone. It slopes back to almost ground level where the rear of the capstone is supdported by a prostrate backstone.

Of course, the most asked question is “how did they get it up there?”.  Well here is my theory.  Most people assume that it was brought here from somewhere else.  Well it was, but by ice.  I think it is a glacial erratic and was dumped here after the glaciers melted about 12,000 years ago.  Somehow, and I have no idea how, the front of the stone was lifted and supported with earth and stones until it reached the height of the portal stones (probably also glacial erratics) which were placed under the capstone to support it. The same would then hav been done with the backstone What we can be sure of is that it was built with sheer druidpower.

Now, time to  Follow Me Up to Carlow. I had to get that in. For those not familiar with the phrase it is the refrain from a 19th century song that describes The Battle of Glenmalure in Wicklow, fought on 25 August 1580, when a Catholic force demolished the British during the Desmond Rebellions. Just love the lyrics including this line….

Carlow lies on the Barrow River, the same river that flows through New Ross and that is guarded by the Hook Head Lighthouse. (Check out my blog on Day 1).  My goal here was Carlow Castle, another of those built by the Norman strongman, William Marshall. It was built around 1210, to guard the vital river crossing.

View of Carlow Castle from the west.

The original structure was pretty unique for Irish castles.  It was rectangular and had towers on each corner and appears to have been modelled on a Norman castle in France.  It survived pretty much intact until 1814 when a Dr Middleton accidentally blew it up in trying to convert it to a lunatic asylum (was a lunatic in charge of the asylum?).  All but the western wall and its two corner towers was destroyed. You do get a bit of a sense of the grandeur of the original building, though from what is left today.

I took a little walk along the river.   Graiguecullen Bridge crosses the Barrow, and dates to 1569 though it was significantly altered and widened since then.

Graiguecullen Bridge dating from 1569 crosses the Barrow.  In the distance is the lime kiln tower of the old sugar factory.

In 1703 the decision was made to make the Barrow navigable.  This involved developing the non tidal stretch of the river from St. Mullins to Athy, (Co. Kildare), a stretch of 68 kilometres and requiring 23 locks. The locks are all functioning today and many have the original stonework.  I visited the lock at Craiguecullen and found an original milestone with the distances to Athy (12 Miles) and St Mullins. After Athy, it links up with the Barrow Line of the Grand Canal for another 45 kilometres, with 9 locks, to the mainline of the Grand Canal. That meant you could travel from New Ross in Waterford to Dublin by boat.  The Barrow ceased to operate commercially in 1959 and is now used for recreation only.

Looking north from the river the skyline of Carlow is dominated by an unusual looking tall steel tower which looks like nothing I have seen.  So I decided to find out what it was.  It was easy enough to locate, but it  but it sits on a wasteland with a high fence around it so I was none the wiser about what it actually was.

carlow castle-2997

Carlow limekiln tower

Turns out it is a limekiln and was part of the infrastructure of a sugar factory.  Yes, really, sugar. Ireland once had a vibrant sugar industry base on sugar beet, and Carlow was the centre of it.  A factory was set up here in 1926 and other factories followed in the 1930s in Mallow, Thurles and Tuam.  By 1936 there were 28,000 farmers growing sugar beet across 22 counties.  At its peak during the early 1980s Ireland produced 220,000 tonnes of sugar a year.   When EU subsidies were withdrawn in 2005 the Carlow plant closed and the only other remaining factory in Mallow also closed the following year, bringing an end to an industry that still supported 4, 000 growers.

The tower is twelve levels tall. Access was by steps around the outside with walkways at each irregularly spaced level.  I have no idea how it works.  Anyone out there know?  All trace of the factory other than the tower is gone.  In 2016 it too nearly disappeared when it was taken off the protected list.  It was saved at the last minute; but the battle between those who consider it part of the area’s heritage and those who consider it an eyesore continues.  A real shame if it is demolished. It would make a totally unique and challenging lookout tower.

Back on the road now to my next destination, a 60km drive to Avoca in Co Wicklow.  A quick stop first, about 20 km from Carlow, for another dolmen.  Haroldstown Dolmen is a beautiful example of a portal tomb and sits in the middle of a field, visible from the road adn easily accessible for a closer look.

My reason for going to Avoca was to check out its mining heritage.  As I have learnt more over the last five years I have been really surprised how rich Ireland is in historic mining sites and I have visited and blogged on a number of these including Arigna in Leitrim, Allihies and Mizen in Cork, the Copper Coast of Waterford, Silvermines in Tipperary and Muckross in Killarney. Really more should be made of in terms of its heritage value.

But as usual I got distracted.  Most tourists visit Avoca to see the Meeting of the Waters, the fabled location where the Irish bard, Thomas Moore, wrote perhaps his most famous song.  So that was my first stop.  The name comes from the site being the confluence of the Avonmore and Avonbeg Rivers to form the Avoca River

There is not in this wide world a valley so sweet
As the vale in whose bosom the bright waters meet,
Oh! the last rays of feeling and life must depart
Ere the bloom of that valley shall fade from my heart.

Meeting of the Waters-

The Meeting of the Waters. The Avonmore and Avonbeg Rivers meet to from the Avoca River, heading off into the distance.

It is a pretty spot there is no doubt. A small park marks the spot, with plenty of reminders of Thomas Moore’s historic presence.  There are monuments and the remains of a tree under which he is said to have written his words.

But for me the most moving ‘monument’ was another tree, this one alive, leaning out over the water.  Evoking the female form, it seemed to capture the spirit of the place.   I call the photo Undressed Timber.  Nature imitating Life imitating Art.

I headed down the Avoca River valley to look for other treasures, lead, silver and copper, perhaps far from Thomas Moore’s mind.  Just a few hundred metres on and I could see a beautifully preserved Cornish Engine House, on the ridge above the valley.  I pulled up next to the Farriers Hotel, another indicator of times gone by.

Cornish Engine House viewed from the Avon River

The Engine houses are a telltale sign that there was an underground mine nearby.  These marvellous buildings are a feature of mining areas throughout Ireland where they housed the steam driven engines that drove the beam pumps used to dewater the mines and to crush the ore.  I find the stone and brick buildings as architecturally impressive as the ecclesiastical ruins that get far more attention in the conventional built landscape.

 

I tried to get closer to the building but I was defeated by a high cyclone fence and the rugged terrain.  The only other remnant of mining at the site are two bins which stored ore before loading into trucks to take to the processing plant.

Mining is believed to have started for copper here, in the Bronze Age (commencing 2,500 BC).  It is believed that it was still a mining centre in 50AD when the location appeared on a Greek map by Ptolomy.  From the 12th to 17th century iron was produced.  From 1750 it was mined for lead and modern copper mining started in 1812.

Continuing my search  I could see plenty of mine dumps and another Engine House from the top of the next ridge, but again I was thwarted in trying to get closer. I am sure there is a road up there but I’ll have to come back when I have more time.

Before leaving the mining area I went to visit the nearby Mottee Stone.  it is a giant granite boulder sitting on the top of a hill with 360 degree view over  the five counties surrounding Wicklow.

avoca-

Mottee Rock and the view over Wicklow

The huge rock is another glacial erratic (like the capstone at Brownshill) deposited by a melting glacier. We don’t know how far the stone was carried but the underlying geology here is slate.  The nearest similar granite is 13 km away at Glenmalure.  Iron rungs have been set into the stone to act as a ladder, which allows you to climb the 2.4 metres to the top.   The story goes that the local landowner wanted to impress his intended wife with the size of his estate, so he got some miners from Avoca to put them there so she could get a better view of the size of his holding.

Cronnebane Mine viewed from Mottee Rock

The most obvious feature in the view though is the large open cut and spoils heaps of the Cronnebane Mine. This is a later phase of mining completed between 1970 and 1982 when 8 million tonees of 0.6%Cu ore was extracted.

Heading towards Avoca village I passed the Old Castlemacadam Church overlooking the Avoca Vale near the village.  It looked different so I stopped.  Built in 1819 for the Church of Ireland it was abandoned after only a short life in 1870.  It is a solid structure with a belfry tower in good condition though unroofed and is surrounded by a graveyard full of interest.

church-3395

Old Castlemacadam Church

I found the external walls of the church interesting too.  They hold evidence of changing aesthetics and a number of different finishes.  The bare stone initially was covered with a render. Sometime later it was covered with a layer of slate shingles cemented onto the render.  Then another layer of render was placed over the top of the slates, leaving them in place.  This was scored with diagonal lines and there appeared to be another thin layer of render over the top of this.  It reminded me of a house I once bought in Leichhardt in Sydney.  I decided to renovate and lifted the carpet in the living room.  Underneath were two more layers of carpet and then a layer of lino over the now rotten floorboards.

As I said the church itself was built in 1819 but the graveyard has many 18th century headstones, the oldest is 1711.  So presumably there was an older church on the site.  No idea whether it also was Church of Ireland.  There are a lot of table grave slabs, way more than I have seen at other graveyards I have visited.   I am wondering if this is more of a protestant thing.

church-3376

Table slab graves

One thing I have seen in many cemeteries is a lack of engraved headstones from the 1840s to the 1870s.  I put this down to the effects of the famines and the extreme poverty meant many could not afford an engraved headstone.  There were often mass graves with no identifation or graves with simple markers that are now just illegible stones.  Here though are a number of engraved headstones from that period that are a poignant reminder of the terrible hurt that was inflicted on many families.  We can tell so much from a simple gravestone.  A couple of examples

John Dowling buried his 7 year old son John in September 1841. He died three years later at the age of 41

34_dowling

The headstone for John Dowling and his son.

Solomon Delaney was patriarch of the Delaney family. He died in 1824 at 63, and his wife Mary followed two years later aged 70.  They had 3 sons. John, Edward and William  Edward died early, in 1927 aged 27 years. Edward’s wife. Mary died soon after in 1829 aged 25. William died in 1843 (47) but was predeceased by his wife Ann as the famine took hold in 1840.    Their daughter Mary also died at this time. The gravestone simply says she “died young”.  John erected the headstone so he survived them all.

And perhaps most poignant of all is John Webster who lost his five children.  Mary (1843) aged 1, John (1846) aged 3, Thomas (1849) aged 6 months, Henrietta (1853) aged 1 day and Nanny (1857) aged 18 years Clearly the ravages of the famine affected catholic and protestant alike.

It was now nearly five o’clock and I was starving so I headed to the village of Avoca for a meal at the local pub.  Fitzgerald’s Pub.

It’s probably familiar to you if you were addicted to the late 90s BBC TV series Ballykissangel, as I was.   Avoca is Ballykissangel.   It was mostly set in this cute village.  Fitzgeralds’ Pub used to be the Fountain but it had a makeover for the show and they just kept it  Across the rooad is Hendley’s Store and the very familiar church up the road where Father Peter Clifford used to hear confession and the Priest’s House which is now a Gift Shop. The curved street will be very familiar to you if you were a fan of  the show.

I had dinner in the pub and just so I felt really at home, episodes of Ballykissangel were on constant reruns on a big screen in the dining room.  I watched Episode 2 of Series 1 when Jenny, an ex flame of  Father Peter arrives in town and sets off the rumour mill while Peter is busy trying to save a caravan family from harassment from Quigley, the town entrepreneur, who keeps dumping manure at the site.  Remember it?  There’s no sound and as I demolish a near perfect beef stew, I follow the action reading the subtitles.

Tempted to stay and watch Episode 3 but I resisted.  One last walk through the town and I was back in the car heading to Bray where I heard there was a session at the Hibernia.  Three days without music and I was starting to suffer withdrawal symptoms.

Bray-3617

The beach at Bray

While I waited I took a walk along the seafront.  A lovely promenade runs the full length of the bouldery beach and the road is lined with cafes, bars, hotels and swish looking tenement houses.  One building of particular interest was owned by Oscar Wilde, who inherited it from his father in 1876.  It was built by Sir William and Lady Jane around 1850, as a holiday home and was later to become the Strand Hotel.

It was a  great night of tunes with musicians Gerry and Paddy and a bar full of interesting people.  After they found out I was Australian, I ended up singing Aussie songs all nght. It was over all too soon and at 1 am I was out on the street.

Bray-3680

Paddy and Gerry, my musical comrades for the night.  

Literally.  I had actually neglected to book any accommodation.  I think part of it was my resistance to paying 99 euro for a night at a B&B.  Prices in Ireland have got ridiculous.  Resigned to a night in the back of the car. I was reluctant to park up on the seafront at Bray so I decided to drive to Sally Gap, 20-odd kilometres away.  Then I would be up on the mountain to catch the sunrise.  So that became Plan A.

While I was playing music however, the sunny day had turned into misty rain and as I gained elevation into the Wicklow Hills, the misty rain turned into foggy misty rain. With the limited visibility I pulled into the first roadside parking bay where there were no other campervans or cars parked  and settled in for, I have to say, a rather uncomfortable night.

I’ll tell you how it all panned out in my final post.

Ireland’s First Copper Mine.  4,500 years of mining history

I have stumbled onto historical mining in a number of places in Ireland in my travels.  Particularly at Allihies and Mizen in West Cork and along the so-called Copper Coast in Waterford.  However, I had no idea of the significance of copper mining in Killarney, and only came across it by chance recently when exploring Killarney National Park’s other delights.

19th Century mining of copper underpinned many fortunes for its British landowners.  In Castletownbere in West Cork,  it was the Puxley’s and Killarney it was the Earls of Kenmare and then the Herberts, who funded their magnificent home at Muckross from their mining wealth.  Ironically the mansion at Muckross was completed in 1843 as the Famine ravaged Ireland.  But the saga of mining in Killarney goes back much further, deep into Neolithic times.

When we talk of mining history in Australia, we think back to the first gold rushes in NSW and Victoria, which were in 1851, or Australia’s own copper boom, which started in South Australia in the 1840s. Mining effectively ended Australia’s time as a penal colony and led to an explosion of free immigration.  So it took a bit to wrap my mind around the mining heritage of a country that goes back thousands of years.

Mining has taken place at two locations on the Killarney Lakes, Ross Island and on the Muckross Peninsula.  Mining there reflects human occupancy from the end of the Neolithic Period and the early Bronze Age (2500-1800 BCE) through Christian times (8th Century) to industrialization in the 18th and 19th centuries.

Ross Island is the earliest known site for copper mining in Ireland.  The activity has been dated by the discovery of Beaker pottery by a team from National University of Ireland Galway in 1992.  The so-called Bell Beaker culture is named after the inverted bell-shaped pottery vessels found scattered throughout Western Europe and dated in Ireland from 2500 BCE to 2200 BCE.  This has been confirmed by radiocarbon dating at the site.

The true Bronze Age in Ireland (that is when copper was alloyed with tin or arsenic to manufacture weaponry and tools) started around 2000 BCE.  Prior to this was the ‘Copper Age’ and copper from Ross Island would have been used for daggers or axe heads or other copper objects and was traded widely.  Chemical fingerprinting and lead isotope analysis shows that Ross Island was the only source of copper until 2200 BCE in Ireland. Not only this, but two-thirds of artefacts from Britain before this time show the same signature.  And Ross Island copper is found to be present in artefacts found in Netherlands and Brittany.  After this time other mines from southern Ireland became more important.

So, Ross Island saw the transition from the Neolithic to the Bronze Age.  Frankly, to me as a mining geologist, to be able to stand on the place where the mining took place that underpinned this highly significant transition in human development in Ireland was, for me, a special experience.

The early miners exploited a rich band of oxidized copper ore within the limestone through shallow cave-like excavations, tunnels and chambers, most of which were damaged by subsequent mining.  Some of the surface ‘caves’ are visible today behind a rusting iron fence though the view is unfortunately heavily obscured by vegetation, which has been allowed to grow unchecked.

These openings were made in the days well before explosives, by lighting fires against the rock face to open fractures and then pounding the walls with stone hammers.  The broken rock was then hand sorted and the separated ore was converted to metal by smelting in pit furnaces.

The last of the first phase of mining from this site is dated at 1700 BCE.  Mining lay dormant for centuries then, but in the early Christian period was a Golden Age of metalworking in Ireland, when such treasures as the Tara Brooch were produced.  Killarney was one of the centers of metallurgical and artisanal skills.  Excavations at Ross Island have found small pit furnaces that date from 700 AD suggesting that ores from here were used to produce metals for the production of  such objects.

Another thousand years passed before the final chapter in the exploitation of the wealth of Killarney copper played out.

This last phase of mining commenced in the early 18th century.  The first attempts at extracting lead in 1707 and then again to work the mine in 1726 failed.  In 1754 Thomas Herbert commenced mining under an arrangement with the then landowner, the Earl of Kenmare.  Mining was difficult due to flooding from proximity to the lake edge and for the next fifty years was sporadic.

I must digress for a moment.  In 1793 Thomas Herbert invited a mining consultant Rudolf Raspe to advise on the mines.  Why do I mention this?  Raspe was German and author of The Fabulous Adventures of the Baron von Munchausen (published in 1785). You might have seen the movie or heard of ‘Munchausen Syndrome’ but I grew up with these fantastical stories read to me by my father. Who would have dreamt of a connection between these far-fetched tales and copper mining in the west of Ireland. Anyway the poor fellow didn’t have such a Fabulous ending dying of scarlet fever a few months later and being buried in an unmarked grave near Muckross.

Meanwhile mining on Muckross Peninsula started in 1749 on the Western Mine and by 1754 the company had raised some £30,000 worth of copper ore, which was shipped to Bristol for smelting.  This closed in 1757 and operations commenced on the Eastern Mine opening for short periods in 1785 and again in 1801.  Operations resumed on the Western Mine in 1795 but these failed due apparently to mismanagement.  Little more was heard of this mine and it was considerably less successful than its neighbour.

But things might have been very different. A dark crystalline mineral was encountered which oxidised to a very bright pink.  It had no copper and so was discarded.  One miner recognised it as the cobalt ore, cobaltite (CoAsS), with its oxidized form, pink erythrite (Co3(AsO4)28H2O).  This man quietly removed twenty tons of this ‘rubbish’ undiscovered.  When the proprietor later realised its value, it was too late.  It had been removed by his helpful employee, or mined as waste and thrown away to expose the copper ore.  Reminds me of the non-recognition of the gold rich Telluride ores in Kalgoorlie in 1893, which for years were used to surface roads, until a way was discovered to extract the gold.  Needless to say, the roads were ripped up.

Back to the Ross Mine, which at the beginning of the 19th century had another renaissance. The Ross Island Company obtained a 31 year mining lease from Lord Kenmare in 1804, Work commenced on the Blue Hole on a rich lode of lead and copper. Mining continued until 1810 by which time it had become unprofitable.

The operation was restarted by the Hibernian Mining Company (1825-9).  Both struggled with the perpetual problem of flooding.  One solution suggested was to drain Lough Leane; this did not go down too well as you can imagine, particularly with the local boatmen.  In the end a large coffer dam was built on the shore and water pumped into it from the mine. Part of the dam is still there.  Bigger and bigger pumps were required and ultimately by 1828 they were unable to deal with the water and the mine closed. Most of the Western Mine area is now flooded as the dam walls have been breached

Wandering over the site today does not give a true sense of the scale of mining in the early 19th century.  This map by Thomas Weaver from 1829 shows the fifty or so shafts, underground tunnels and surface buildings from this phase of operations.

But mining grew out of favour and conflicted with the rise of tourism to the area.   No more mine leases were granted after 1829 by the Herberts, who by this time had transitioned from mining entrepreneurs to landowners. The area was carefully landscaped, with the infilling of shafts, flooding of the Blue Hole, the demolition of buildings and the planting of trees. Subsequent forest growth has softened the historic footprint of the mining

Mineral exploration is now prohibited in the National Park so the remarkable 4,500 year history of mining here has come to an end.  Public awareness however of this important site is increasing with the creation of a Mining Trail and explanatory signage at the site.  To me, places like this are as important as Glendalough and Ceidi Fields and their preservation is so important.

I am ashamed to say that after five years in Ireland I only discovered this place by accident.  But find it I did, and I will be back there as soon as I can be.

 

Much of the material for this blog came from the informative website of the National University of Ireland Galway who completed the archaeological study of the historical mining sites in 1992.   http://www.nuigalway.ie/ross_island/.  My thanks and acknowledgement to them.

The Beach at Allihies, Co. Cork. A Beautiful Legacy of Ignorance and Indifference.

Allihies is a very photogenic village near the tip of the Beara Peninsula. I have blogged on it before (click here).   There I gave an overview of the whole Beara Peninsula as well as highlighting the extensive history of copper mining in the area,  but I didn’t mention the pretty beach near Allihies, which I didn’t visit last time.

IG3C4137

The beach at Allihies

Back in the Beara recently, I had a bit more time and found myself on the strand during a break in the bleak weather.  This beautiful place has a very interesting back story and an unexpected connection to the mining operations located high up in the hills above the village.

The beach is a surprise.  It seems like it shouldn’t be there. The whole coastline here is rugged and rocky and apparently too wild for sand to accumulate.  And yet there it is, an extensive thick accumulation of golden sand in a protected inlet.

Sand, water, rocks and sky

A close look however shows all is not what it seems.

The sand is very coarse.  It is also very uniform in size and it only comprises fragments of quartz and shale.  There are no organic bits or shell fragments as you would expect.  In fact is unlike any beach sand I have seen.  There are no dunes; just a thick deposit of banded unconsolidated coarse sand.  And due to the lack of fines, it is not compacted as might be expected. It is very hard to walk on and especially hard to climb its slopes.

Coarse sand.  Lots of quartz and rock fragments

So where did it come from?

This is where the mining comes in.  Copper mining took place at Allihies for over 70 years starting in 1813.  In its day it was the largest copper production centre in Europe.   Allihies was remote and there were no environmental or safety controls and the Mine Captains pretty much did what they liked.  So rather than build an expensive dam to contain the tailings they were pumped into the local rivers that eventually found their way to the coast at Ballydonegan.  Standard practice then.  Environmental vandalism today.

So what are tailings?  In hard rock mining the rock containing copper minerals is brought to the surface for processing.  The total percentage of copper minerals may only be about 2-5% so over 95% of the rock mined must be disposed of.  It is crushed and then the copper minerals are separated with the remainder of the rock disposed of.   It was lucky that the processing this time didn’t involve toxic chemicals so the tailings was reasonably clean.   It accumulated at the mouth of the river and eventually the Atlantic Ocean converted it into a beach.  The vast majority of visitors are probably totally unaware that it is man-made.

It is a pretty place.  A great safe swimming beach and stunning views.  It is ironic though that in the 21st century it is one of the attractions of the area whereas two centuries ago it would have been a major blight on the landscape and that a place of such beauty exists because of man’s indifference and ignorance.
