Building Stones of England: Hertfordshire

This guide is one of a series for each English county. The guides draw on research and fieldwork with the British Geological Survey, geologists and building historians to compile the Building Stones of England Database.

The guides are aimed at mineral planners, building conservation advisers, architects and surveyors, and those assessing townscapes and countryside character.

The guides will also be of interest if you want to find out more about local buildings and geology.
