About Us
Vertical Divider
We are a small group of amateur and retired professional geologists who wish to investigate, publicise, celebrate and archive information about the building stones used in Dorset's historic churches and buildings. Many of us also belong to other groups such as:
Dorset Geologists Association Group (DGAG), Open University Geological Society (OUGS), Dorset's Important Geological Sites group (DIGS), Dorset Environmental Records Centre(DERC) and the Dorset Buildings Group (DBG).   
Please note that whilst we make every effort to be accurate in our identification of building stone types we cannot guarantee 100% levels of certainty. Even geologists are fallible! The purpose of our study is to identify the stone used in historic buildings while exploring the County and enjoying ourselves immensely! The purpose of the website is to add to the sum of knowledge about historic buildings.
