I looked at an old (18thc) parish boundary map recently which marks a "cave" adjacent to the Wychbury site.
Hi Hedgerider, could you tell me the source of the map please? This is interesting. I'm wondering if it may be Saddleback hill on the N/W side of Wychbury which I think has some kind of spring issuing, or used to. Maybe there was once a hole in the side? I can't think of any 'caves' proper though.
Will scan memory banks for Harborough Hill sources :-)
