Summary

Partial contour multiple enclosure located on summit of hill on N side of River Teign and between two steep gorges where a tributary joins the river. Commanding position with very steep to precipitous slopes to S quadrants and W, steep to NW and N and moderate to NE. Defined by a main inner enclosure rampart surrounding the summit of the hill, with two additional widely-spaced ramparts in two arcs downhill to the NE, middle bank much nearer main circuit than outer. Main enclosure bank almost non-existent on steepest SW side, with bank to 1.2m high and no ditch elsewhere. Site ploughed in past with some quarrying, so possible that ditch now a buried feature, but uncertain. Bank appears to have been scarped below in some places, so adding degree of monumentality. An E entrance nearly lines up with entrance of middle and second rampart downhill, which, on N side, seems to be merely a break of slope. Further downhill, the outer bank sweeps round in an arc from N to SE. Bank is substantial in places with large ditch, but mere break of slope to N and non-existent where it meets the precipitous Teign gorge on SE. It has a fine inturned entrance to NE and at this point bank rises to c. 3m high plus. Inner enclosure c. 1.4ha, second enclosure extends this to 2.6ha with the outer enclosure being c.9.0ha. Much debate as to whether these widely-spaced banks indicate a phased development of the site or not, a similar situation at Cranbrook (Atlas No 3347) sited directly across the Teign. Ploughing has certainly affected the site to its detriment and now under improved pasture. On 1st Ed. OS map (1885). Minimal investigations, undated.

Enclosing Works

Defined by a main inner enclosure rampart surrounding the summit of the hill, with two additional widely-spaced ramparts in two arcs downhill to the NE, the middle bank much nearer the main circuit than the outer. Main enclosure bank almost non-existent on the steepest SW side, with bank to 1.2m high and no ditch elsewhere. Site ploughed in the past with some quarrying, so possible that ditch now buried feature, but uncertain. Bank appears to have been scarped below in some places, so adding a degree of monumentality. Middle and second rampart downhill, on N side seems merely a break of slope. Further downhill, outer bank sweeps round in an arc from N to SE. Bank is substantial in places with large ditch, but mere break of slope to N and non-existent where it meets the precipitous Teign gorge on the SE.

Total:   9.0ha.
