The monument consists of the remains of a Roman rectangular courtyard building dating to the 2nd or 3rd centuries AD. It is located close to the beach at Cold Knap with expansive views over the Bristol Channel. Stone footings survive on the northern part of the site up to four courses high. Located in the south-east corner is a cellared room.

The monument is of national importance for its potential to enhance our knowledge of Romano-British settlement and socio-economic organisation. The feature forms an important element within the wider context of Romano-British society in Wales and retains significant archaeological potential. Such Roman buildings are often part of a larger cluster of rural and urban settlements and their importance can further enhanced by their group value.

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