THE drystone walls that criss-cross the Dales are rich sources of information about the past, as landscape archaeologist Dr David Johnson will explain in a talk in Ingleton.

The talk takes place on Monday, October 16 at 7.30pm at Ingleborough Community Centre, Ingleton, hosted by Ingleborough Archaeology Group.

Dr Johnson will give fascinating insights from one of the most comprehensive archaeological drystone wall surveys undertaken anywhere in the country in which he led a team of volunteers to record the features of 37 different walls.

The survey reveals how walls can be interpreted to give clues about the development of the landscape over many centuries, with some walls dating back 400 years or more. The study focused on walls in the Westmorland Dales. A display of recent projects by the archaeology group will be on show from 7pm and the talk will be followed by the AGM.
