The monument comprises the remains of a motte and ditch, dating to the medieval period (c. 1066 -1540 AD). The motte is located in a field immediately S of the A40. It is a steep-sided conical mound, 3.5m high, with a flat top 10m in diameter. There is no evidence for a ditch surrounding the motte.

The monument is of national importance for its potential to enhance our knowledge of medieval defensive practices. The monument is well-preserved and an important relic of the medieval landscape. It retains significant archaeological potential, with a strong probability of the presence of both structural evidence and intact associated deposits.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
