This square, grass-covered enclosure measures approximately 27.5 metres on each side and is defined by earthen banks and scarps that have survived the centuries. The northern boundary and part of the eastern side feature a scrub-covered earthen bank that’s about 4 to 5 metres wide, rising from 0.4 metres high on the eastern end to 1.6 metres at its northern point. The internal height varies considerably, whilst the external face stands at roughly 0.95 metres.

The western and southern boundaries of the site are marked by scrub-covered scarps rather than built-up banks, with heights ranging from 0.7 metres on the western side to 1.5 metres along the southern edge. Interestingly, there’s no evidence of a fosse or moat surrounding the site today, despite its classification as a moated site; this defensive feature may have been filled in over time or might never have been fully developed.

These types of earthwork enclosures were typically constructed during the Anglo-Norman period in Ireland, serving as fortified homesteads for settlers or as administrative centres for managing agricultural estates. The site at Kye, with its well-preserved banks and clear square outline, offers a glimpse into medieval settlement patterns in this part of Roscommon, where the landscape still bears the marks of centuries-old defensive structures.
