Can we date Mendip's Dry Stone Walls?
This pilot study was undertaken by members of CHERT (Charterhouse Environs Research Team) from September 2007 to March 2008 to establish whether it was possible to identify different styles of stone walls through the historical period. A combination of fieldwork, drawing and documentary research was used to try to establish a wall typology that could be tested in the field and used in other parts of the Mendip Hills AONB.
