Summary

Situated NE of Peakirk, a low lying bivallate near circular enclosure of 300m diameter and 3.8ha, cut N-S by a modern road, on a penisnsular projecting into the Fen. Earthworks much denuded by ploughing to the E of the road. The main inner bank is 7.5m wide at the base and 1.5m high, has a berm 1.5m wide separating it from the ditch which is 2.3m deep and 10.5 m wide across the top. The ditch of the outer rampart survives as an earthwork heavily abraded by ploughing, for a total of 400m along the N and W sides of the enclosure. The ditch is 1.3m deep and 3.5m wide across the top. Possible contemporary features are represented by four closely-spaced ditches set 2m apart and running parallel to the W edge of the enclosure. A slightly in-turned entrance on the E side, through both banks, is probably original. Later features comprise a relatively broad and abraded bank between the inner and outer rampart, which appears to represent re-deposited soil removed from the bank. A series of ditched rectangular depression to the SW of the enclosure are likely to be post medieval quarries with associated drainage ditches, possibly contemporary with the construction of the road in the 19th century. Limited augering and excavation (French 1988; French and Pryor 1993) demonstrated the survival of a well preserved buried soil and a major phase of occupation, sealed by alluvial deposits of probably Roman date. In 1991 the Ancient Monuments Laboratory carried out satellite photography and resistivity survey. In 1992-3, limited excavation was carried out along the sides of Redcow Drain, and sections through both ramparts were exposed showing possible timber revetting (Malim and McKenna 1993). Organic material and Middle Iron Age pottery (3rd - 2nd century BC) were recovered from the water-logged primary fills of the main ditch. During a survey in 1993 a total of 13 sherds of probable Middle Iron Age pottery were found (Oswald 1994). Scheduled as Roman or medieval but shown to have been constructed in the Middle Iron Age, then abandoned with cultivation across the interior, flooded in Roman times. Described as 'one of the best preserved Iron Age sites in the country' due to it water-logging and potential for evidence.
