A 12th century motte and bailey castle. There is only documentary evidence for a bailey but the motte is about 20 feet high and looks much like a barrow. (Pastscape)
The remains are visible from the road.
There was in Goldington, two miles N.E. from Bedford, on the Ouse, a possession of the Beauchamps, though supposed by Leland to have been attached to the castle of Walter le Spec, the founder of Warden Abbey in 1135. (He also founded Rievaux, in 1131, and Kirkham, in 1121, Yorkshire). There is a vast mound on which a Saxon keep, and perhaps one of later date, may have been erected, and there are earthworks adjoining it, but no foundations of walls or masonry have been found. It seems possible that this was originally a Saxon fortification raised at the time of the Danish invasion at Tempsford, and a connecting post between Bedford and Eaton Socon.
