The castle is believed to have been built after the Norman Conquest.
The castle was a small circular ring-motte fortification, once measuring 35 yards across, now only 25 yards, with a high motte, or mound, in the middle and a protective ditch around it.
[1] The entrance to the castle was on the south side of the fortification.
[2] The castle would have defended the Stowe valley, and was probably a precursor to the later St Briavels Castle in the same area.
