Beer Quarry Caves are a man-made underground complex located a mile west of the village of Beer, Devon. The tunnels resulted from 2,000 years of quarrying Beer stone, which was particularly favoured for the cathedral and church features such as door and window surrounds because of its colour and workability for carving. Stone from the quarry was used to construct several of Southern England’s ancient cathedrals and other important buildings, as well as many town and village churches and some buildings in the United States. Extraction was particularly intense during the Middle Ages the quarry closed in the 1920s.
Today you can visit the caves on an hour-long underground tour through the vast man-made complex of underground caverns There are large halls with vaulted roofs and pillars of Beer Stone which have been likened to a vast underground cathedral.
Continued Reflections from my World. 
I had to look up what kind of rock it is? It’s a fine grained Limestone, which has the unusual property of hardened once exposed to the open air. So many carvings were done down in the caves.
I see they do not do the tours in winter because many bats winter over in them, including one very rare bat.
Interesting spot!

Yes Wayne I have some years ago I think it is National Trust building {the beam engine house.} The accident is one that is often quoted of how H&S in early mining was poor. When I visited one coal mining museum in Wales, after a disaster the mine owner was more concerned with how many pit ponies had died over men as they worth worth more! I do like the Tin Mining Engine Houses you find in Cornwall you have to be careful as some of the shafts are not well marked!
