Fascinating to see these tunnels and all the artefacts found when clearing them out. Also fascinating to hear about the very eccentric Joseph Williamson.
Our guide, Clare, was a passionate volunteer who has been involved in exploring and clearing out these tunnels for many many years.
FoWT do not have a slick visitor centre - just a portakabin (and a portaloo) - but the volunteers are clearly very knowledgeable, experienced and passionate enough to give their time for free tours.
A quirky, unique experience - definitely worth the visit.
