Bath Stone is an Oolitic Limestone comprising granular fragments of calcium carbonate. Bath Stone was originally quarried from the Combe Down and Bathampton Down Mines under Combe Down, Somerset, England. It has a warm, honey colouring giving the City of Bath its distinctive appearance. Bath Stone is a freestone, which means it can be sawn or 'squared up' in any direction, unlike other rocks such as slate which forms distinct layers.
Bath Stone has been used extensively as a building material throughout southern England for churches, houses and public buildings such as railway stations.
Some of the quarries from which the stone was taken are still in use today.
