Dolebury Warren

Dolebury Warren is a 90.6-hectare (224-acre) hill fort and biological Site of Special Scientific Interest (SSSI) in North Somerset, South West England [1]. It is owned by the National Trust, who acquired the freehold in 1983, and managed by the Avon Wildlife Trust [1]. The massive earthworks enclose one of the largest hill forts in Britain, with the ramparts reaching up to 10 metres high in places [1].
