The earthwork mound reaches four metres in height, with a flat top measuring 17 metres across and a base spanning 28 metres in diameter. Around its perimeter, you can still trace the remains of a defensive ditch, or fosse, which runs 11 to 13 metres wide though it’s now only about 40 centimetres deep, softened by centuries of weathering and overgrowth.

The castle motte occupies a strategic position on slightly elevated ground, with the River Blackwater flowing north to south roughly 600 metres to the east and the coastline lying about 900 metres to the southeast. This placement would have given its Norman builders clear sightlines across the surrounding lowlands whilst maintaining proximity to both river transport and coastal access, essential considerations for medieval military architecture.

Just northwest of the main mound, the remnants of what appears to be a triangular bailey can still be discerned in the landscape, measuring approximately 30 metres along both its northeast to southwest and northwest to southeast sides. This secondary enclosure would have housed the garrison, stables, workshops and other structures necessary for the daily operation of a Norman fortification. Today, nature has largely reclaimed the site, with vegetation obscuring much of the earthwork’s original sharp definition, though its fundamental form remains readable to those who know where to look.
