340 million years ago – during the complex geological history of south Donegal – a short scarp of golden-yellow carboniferous sandstone was formed.
I head off to the mines in Drumkeelan, which were in operation up until the 1950s
The twenty-foot deep stone mine roof is supported by waste stone packed into pillars
I’m with Brian Kerrigan, family quarryman.
He shows me ‘free stone’ – stone free from cracks and clefts – the fare of these mines for many centuries, supplying famous buildings such as The National Museum of Ireland, The Dail and Stormont.
Here is Brian’s donation of a truckload of finest Drumkeelan stone for The Gathering of Stones
Thanks a million – from everyone at The Dry Stone Wall Association of Ireland.
Off to the center of Ireland with these Donegal stones – and a circle we shall build.
