Univallate, partial contour hillfort, located on high rocky promontory at SW-facing end of steep-sided ridge on N side of lower Barle valley and above a significant meander of the River Barle, just S of its confluence with Danes Brook and its steep valley on W, within Mounsey Wood. Very steep to precipitous slopes to river on W side, steep to river on S and moderate to strong along ridge to NE. Overlooking valley and river, similar to Brewer's Castle opposite and across the river to NW (Atlas No 4127), Cow Castle (Atlas No 4112) upriver and Oldberry Castle at Dulverton (Atlas No 4118). Triangular shape broadly follows the contours, with a wide curved base to S narrowing to N, with interior area c. 1.75ha. Defined by single tumbled stone scarp on E and W and rampart with ditch and counterscarp on S varying between 1.5m and 2m high. On S and W sides escarpment artificially emphasised by internal scarp appearing to have been quarried to provide material for the rampart. Revetment walling visible in rampart face along S side, which is to 0.8m high and constructed of roughly coursed stone. Defences on N provided by substantial outwork, c. 100m away, and straddling the steep ridge which forms the narrow, N rocky spur of the hill. Outwork c. 16m wide and formed by modification of the ridge to form a steep stone-faced scarp with shallow ditch behind and fronted by a level berm with scarped bank below, also stone-faced, extending for c. 30m across the ridge. Strategically placed to defend an entrance on N side. There are two original entrances, to NE and SW. Former has slightly out-turned rampart with berm and short length of bank. SW entrance formed by one in-turned, and one slightly out-turned, rampart end creating an embanked corridor into interior. Remains of charcoal burner's hut in interior, activity supporting local iron working. Mounsey Castle takes its name from Monceaux family, local landowners in medieval period. Legend has it that a stone at Mouncey Castle fell from the Devil's apron as he was on his way to build Tarr Steps. Scrub and bracken interior. On 1st Ed. OS map (1890). Few investigations. Undated.
