Inland promontory fort located on a small SE-facing promontory overlooking a stream confluence above Sandyhaven Pill. Steep slopes to E, S and W, moderate along promontory on N. Triangular enclosure measuring c. 140m N-S by 80m, with internal area 0.36ha. Steep valley sides provide protection on E and S sides. On W, above a shallower stream valley, single bank, probably topped by palisade, but main defence is on N where neck of promontory cut off by three lines of ramparts. Inner and middle close-set, but outer c. 20m to N, forming an annexe or an earlier or later phase of the site. Banks stop short of slope at NE end and here possible entrance, but disturbed. Possible reoccupation in medieval period. Here inner and middle rampart remodelled to create a mound at E end of the ramparts. Hollow inside this mound suggests structure on top. Detailed survey undertaken 2007 by RCAHMW and local societies. Pasture interior and main and inner banks, with annexe defence under hedge. Wooded surrounds. On 1st Ed. OS map (1874-1875). Undated.
