The Chestnuts are well worth the visit, we spent a very interesting hour being shown around the site by the woman who lives at the house. The dowsing was fun, having never done anything like it before I really enjoyed it. If you have time ask to see the womans collection of stone and flint tools, it made such a difference being able to hold them, rather than just having to be content with looking at them through glass in a museum. For those who don’t know, the site visit is by appointment only, we didn’t know this before hand, but were lucky that the woman was free to show us around, so it may be best to check before going.
