Around the Tor are Iron Age earthworks, the remnants of a Hill fort. Unusually, the fortifications are at the base of the Tor, rather than the summit as is more normal (compare with Brent Knoll in Somerset). No serious archaeological work has been carried out on the site. However, the northern ramparts in particular are well preserved, displaying a multi-vallate pattern characteristic of the Iron-A, or early -B, culture. There are three distinct consecutive ramparts in this sector, and traces of internal partitioning.
