This roughly square earthwork, measuring about 41 metres north to south and 40 metres east to west, rises from the boggy ground with scarps reaching up to 0.6 metres in height. Today, thick gorse bushes have claimed the site, making it difficult to explore, though faint traces of old ridge and furrow patterns running east to west can still be spotted in the interior.

The site’s more recent history is well documented; the first Ordnance Survey map from 1840 shows it was once an osiery, a plantation where willow trees were cultivated for basket making and other crafts. These ridge and furrow marks likely date from this period when the wet conditions would have been perfect for growing osiers. By 1953, the OS maps depicted the site differently, showing it as a partially hachured square enclosure labelled ‘Lisheen’, suggesting its use had changed or been abandoned by then.

What makes this site particularly intriguing is its traditional association with the name Lisheen, which in Irish typically refers to a small fort or ringfort, and its location just half a mile southwest of the medieval settlement at Moyaliff. While the documented history points to its 19th century use as an osiery, these connections hint at the possibility of much older origins. The raised platform’s defensive position, surrounded by natural water barriers, would have made it an ideal location for an early medieval fortification or settlement, perhaps later repurposed for willow cultivation when such defensive structures were no longer needed.
