This rectangular earthwork, measuring 55 metres east to west and 37.6 metres north to south, consists of two earthen banks with a water-filled ditch, or fosse, running between them. The modern road appears to have cut through the eastern section where the fosse and outer bank once continued, whilst traces of the outer defences remain visible along the southern and western sides. A small channel at the northwest corner may have served as a leat, directing water into or away from the moat.

The interior of this defensive enclosure contains intriguing evidence of past occupation. Near the southeast corner, close to the inner bank, archaeologists have identified a small rectangular depression approximately 6 metres long, which may mark the location of a former structure. More remarkably, an oval feature measuring 6 metres north to south and 5.5 metres wide sits atop the inner bank on the south-southwest side; this likely represents the remains of a dwelling house, strategically positioned on the raised earthwork for added security and visibility.

The landscape surrounding the site tells its own story of medieval land management. To the northwest, the ground becomes boggy, whilst a stream flows from northwest to southeast along the northern boundary. These natural water features would have supplemented the defensive moat, creating additional barriers to unwanted visitors whilst providing a reliable water source for the site’s inhabitants. Such moated sites, typically dating from the 13th to 15th centuries, were often home to Anglo-Norman settlers or prosperous Irish families who adopted this defensive architectural style during a period of considerable social and political upheaval.
