The monument consists of a settlement dating to the Roman period (AD74-410). Located to the east of an old flooded quarry, a series of grass-covered hollows and banks can be discerned. Where the site meets the edge of the disused quarry, an occupation layer with indications of walls is visible. Roman pottery has been recovered from the site.

The monument is of national importance for its potential to enhance our knowledge of Roman settlement organisation. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits.

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