Beer Quarry Caves, a vast complex of man-made caverns created by centuries of quarrying Beer Stone. Originally worked by the Romans, supplied stone for 24 cathedrals including Exeter and St Pauls. Beer stone is ideal for fine detail carvings, but hardens when exposed to the air. A small museum is housed within the Roman section of the caves containing pieces of carved Beer stone, tools, ancient documents and photographs. See the methods used to quarry and deliver the huge blocks of stone, the working conditions and the hardships and dangers endured by the work-force.
