Summary

A large univallate hillfort lying directly to the S of Arlescote at 210m OD on a narrow, jutting promontory of the Edge Hills scarp. It is sub-oval in form with maximum dimensions of 360m by 243m enclosing 6.9ha with the ground sloping away steeply in all directions. A plan drawn in 1882 shows two ramparts and a medial ditch, the outer rampart is now interpreted as a counterscarp bank. It was extant on aerial photographs in 1947 but almost plough-levelled by 2007, although in places the ramparts survive in varying states of preservation and as scarps up to 2m high within the modern field boundaries. The ditch, now in-filled and in the N, underlies the modern road. A probable entrance, approached by a holloway, lies in the W with out-turned terminals. A series of parallel crescent-shaped banks in the region of entrance once interpreted as an annex (Thomas 1974), are now thought to be an elaboration of the entrance. This description is contradicted by McArthur (1987-8) who describes a single inturned entrance in the NW. Seventy fragments of Iron Age pot and other finds were recovered during a survey (French 1981). A small excavation by Birmingham University Field Archaeology Unit across the northern defences in 1983 (McArthur 1987-8) showed the rampart was of dump construction on a stone platform with a rear kerb of large stones. The front face was destroyed by a large quarry pit and no evidence could be found for the ditch in that area. Large pits were discovered, one underlying the rampart and a second, which cut the rampart, showing at least one earlier phase and subsequent remodelling. A currency bar was recovered from one of the pits along with bone, pottery and slag. The finds assemblage and radiocarbon dates suggest a date of construction for the rampart within the central two centuries of the first millennium BC. A resistance survey of part of the interior indicated that considerable evidence for occupation survived within the interior McArthur (1987-8). The interior is now divided into two arable fields. A watching brief ahead of a water main work in 1997 and 1998 by Warwickshire Museum Field Services produced no further finds (Coutts, 1997; WMFS 1998). A beehive quern was found in the 1960's and field walking by Edgehill Group in 1999 recovered an assemblage of predominantly early Iron Age pottery together with flint from several different time periods (Wager 2002). The site is recorded on 1885-1900 OS mapping. Scheduled

Interior Features

Resistance survey suggests there is considerable surviving evidence for activity within the interior. Excavation concentrated on the rampart but showed internal pits. A currency bar was recovered from one of the pits along with bone, pottery and slag.
