Sherborne stone is an unusual but beautiful stone, it is natural limestone that for centuries has been used as the main building material of the ancient town of Sherborne in Dorset.
It is a honey coloured Inferior Oolite sandy limestone with creamy parts from the Bajocian age of the Middle Jurassic geological period laid down some 160 to 170 million years ago during the Mesozoic era.
The stone was formed in a shallow tropical sea similar to the conditions found in shallow tropical seas today. The stone contains a mixture of calcium carbonate (lime) from fossilised sea creatures and fine sand from the sea floor all of which have been mixed together to form a hard fine grained sandy limestone.
Sherborne building stone comes from a reopened quarry on the edge of the exposure to the east of the town. It has been used for a variety of internal and external uses for many centuries and it is also a good match for similar outcrops of Inferior Oolite stone used for building in many other towns and villages of Somerset and Dorset.
