At 390 feet above sea level, this medieval earthwork consists of a roughly rectangular area protected by an impressive series of defensive features: an inner bank, a fosse (or defensive ditch), and an outer bank. The site has been recognised for its historical importance since 1989, when it was added to the Register of Historic Monuments.

The inner defensive bank, built from earth and stone, has become part of the local landscape over the centuries; its eastern side now forms a townland boundary running north to south. Though time has reduced much of the northern and southern sections to mere scarps, careful observation reveals traces of the original dry stone facing on both the interior and exterior walls. The northwest and southwest corners rise slightly higher than the rest, hinting at possible watchtowers or reinforced defensive positions. Between the inner and outer banks lies the fosse, a wide, shallow ditch with a characteristic flat bottom that would have presented a formidable obstacle to any would-be attackers.

The outer bank has fared less well than its inner counterpart, with the southern section almost completely levelled. However, remnants of internal stone facing can still be seen at the northwest corner and along the northern side. While the original entrance has been lost to time, gaps at the northeast and southwest corners of the inner bank may indicate later access points. Within the protected interior, which slopes gently eastward, archaeologists have identified the remains of four house sites, suggesting this was once a thriving defended settlement rather than purely a military installation.
