The main feature is a raised earthen enclosure measuring 23 metres north to south and 25 metres east to west, surrounded by a substantial earthen bank that rises nearly 3 metres on its exterior face. A wide entrance, almost 9 metres across, opens to the south, providing access to what would have been the castle’s primary defensive position.

The fortification’s defences are enhanced by a fosse, or dry moat, that curves from south-southwest to north to south-southeast around much of the structure. This ditch measures approximately 8.85 metres wide and 1.35 metres deep, creating an additional barrier between attackers and the inner enclosure. Beyond the fosse lies an outer bank, equally impressive at nearly 13 metres wide and over 2 metres high on its inner face, which extends into a semi-circular bailey measuring 24 by 15 metres. This bailey would have served as an outer courtyard, providing space for various activities and additional protection for the main fortification.

Today, the monument shows considerable wear from horses using the pasture, with deep poaching evident throughout the site. The interior of the enclosure tilts slightly downslope towards the south, following the natural contour of the land. Two other historic enclosures can be found nearby; one lies 370 metres to the east-southeast, whilst another sits 440 metres to the west, suggesting this area held strategic importance during the medieval period. Despite the damage from centuries of agricultural use, the earthworks remain clearly visible, preserving the footprint of this once-formidable defensive structure.
