This rectangular earthwork, measuring 32 metres east to west and 26 metres north to south, sits within the northwest corner of a much larger enclosure, both clearly visible in aerial photographs from 2002. The site’s defensive features remain remarkably well-preserved, with low earthen banks still standing up to 2.8 metres wide at the top, though they’ve been reduced to mere scarps along the eastern and western sides.

The surrounding fosse, or defensive ditch, varies in width from roughly 5.9 to 6.1 metres and reaches depths of up to 20 centimetres on the northern side. Interestingly, this northern fosse extends beyond the monument itself, continuing northeast down the precipice slope where it appears to cut through the boundaries of the larger enclosure. To the north, another enclosure shares this intervening ditch, suggesting a complex relationship between these neighbouring sites that hints at different phases of construction or concurrent use.

Perhaps the most curious feature lies immediately east of the main moated area, where the larger enclosure has been internally divided to create a D-shaped annexe measuring 26 metres north to south and 23.5 metres east to west. This secondary space is defined by the curvilinear scarp of the main enclosure and a levelled linear scarp with its own fosse to the south. Both the main site and this D-shaped area slope gently eastward, following the natural topography of the landscape. These earthworks, compiled and documented by Jean Farrelly in August 2011, offer valuable evidence of how medieval communities organised and defended their settlements in this part of Tipperary.
