The monument comprises the remains of a motte and ditch, dating to the medieval period (c. 1066 -1540 AD), together with the remains of two post-medieval house platforms. A motte is a large conical or pyramidal mound of soil and/or stone, usually surrounded by either a wet or dry ditch, and surmounted by a tower constructed of timber or stone. This site, which is also known as Bogs Mound Castle, occupies a low-lying position in marshy ground in the valley of the Knobley brook, at the east end of the Walton basin. The motte stands to a height of c.3.6m and has a top diameter of c.16m. The bailey was probably on the north-east side, where faint traces of a bank occur c.45m north-east of the ditch surrounding the motte. The stream and marshy ground adjoining it would probably have provided adequate defence against any attack on the west. The two post-medieval house platforms lie on the south-east of the motte.

The monument is of national importance for its potential to enhance our knowledge of medieval defensive practices and post-medieval settlement. The monument is well-preserved and an important relic of the medieval and post-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.
