The motte at Castle Hill, Halton sits within the village on the end of a spur formed by the valley of the Cote Beck, the land descending steeply on the south to the Lune, and the southwest to the beck ( see map ). The motte is about 95m in diameter and rises some 3.2m above the level of the bailey, which is to the northeast. The truncated top of the motte measures about 11m across and has been damaged by the construction of a lookout post in 1939 and by a more modern flagpole. The crescent-shaped bailey still retains traces of a rampart and of the ditch that divided it from the motte but slight remains of the external ditch are only visible on the north side. The parish church with its Anglian crosses and dedication to St Wilfrid is clearly a pre-Conquest foundation and lies below the castle on the opposite side of Cote Beck.
