Bath Stone is an Oolitic Limestone comprising granular fragments of calcium carbonate. Originally obtained from the Combe Down and Bathampton Down Mines under Combe Down, Somerset, England, its warm, honey colouring gives the World Heritage City of Bath, England its distinctive appearance. An important feature of Bath Stone is that it is a freestone, that is one that can be sawn or 'squared up' in any direction, unlike other rocks such as slate which forms distinct layers. Ham and Doulting Stone Ltd reopened the Park Lane Underground Quarry in Corsham but has recently sold the lease to Park Lane Bath Stone Ltd owned by Blockstone. However, we continue to supply Park Lane to our customers and, with its fine texture and ease of working, the stone is very popular with masons.
