A panoramic photograph showing a group of people - the delegates at the Heritage Stone Workshop - standing in front of the active Threecastles limestone quarry in Kilkenny. We are all wearing hi vis vests and there are around 35 of us. The photo was taken by C Sreejith.

I have just come back from the 4th Round International Heritage Stone Workshop in Ireland. Here we all are at #McKeoneStone’s quarry at Threecastles in Co Kilkenny

A view of us, wearing high vis jackets, walking through the stone mine. The tunnels are more or less square in section and recede into the distance

Block is also stored in the mine until it is needed. One of our team is standing between two fresh cut blocks which are taller than her.

A close up of a rare facies of Portland stone - oyster and Solenopora patch reefs occur in the Portland stones and are only revealed by quarrying.

A close up of Bowers Roach - a facies of Portland Stone with distinctive and characteristic casts and moulds of fossils, including the spire-shaped gastropod Aptyxiella portlandica shown here.

A visit to the Jordans/Bowers #PortlandStone Mine for the @stone-work.bsky.social team. We had a fantastic tour from #AlbionStone. An incredible opportunity to see these exposed faces of pristine Portland Formation - Britain’s global heritage stone #buildingstone #ghs #isleofportland

My well trained family send me photos of paving stones when they are on holiday. These are in Venice... I reckon bricks, what do you think? #urbangeology #buildingstone #paving

A piece of rough, unpolished black limestone being held in a pair of hands

The Kilkenny ‘black marble’ facies at Butlersgrove Quarry. Black, fine-grained, fossil-free limestone which takes a high polish #buildingstone #decorativestone
