Hockliffe Manor is a moated, earthwork enclosure on the edges of the village of Hockliffe, Bedfordshire, that probably once surrounded a medieval manor house, and was possibly constructed in the 13th century.
The earthworks lie around 100 m to the west of the modern village. The earthworks form a square platform, approximately 80 m across, built up from the natural hillside. Within it is an oval mound, approximately 30 m by 28 m, with a low bank around its perimeter. The mound is protected by a ditch, up to 4 m wide with an outer bank up to 0.8 m high and 2.5 m wide, effectively forming a dry moat. The site would have been entered from the south-west. Earthworks suggesting a wider settlement lie to the north, west and south of the site, including a large terrace, 50 m by 10 m wide, to the north-west that probably held further buildings.
Archaeological excavations in 1909 showed that the site had been occupied in the medieval period, and the history of Hockcliffe Manor suggests a 13th century date. The earthworks would then have formed a fortified manor house or manorial centre, with buildings filling the area outside the mound, and the site as a whole surrounded by fields and other buildings.
The site is protected as a Scheduled Monument under UK law.
