From Portland Stone to Millstone Grit, Historic England is launching a new online database of the stones that define the rich diversity of our country’s buildings. Historic England is unveiling the first Building Stones Database for England, which brings together information on over 4,000 types of building stones, their uses and sources, in a searchable online GIS map explorer. Users can browse the geological map, search by postcode, address or place name as well as looking for a specific building stone, representative buildings or structures made with each stone type, and stone sources.
