This ancient fortification, measuring 45 metres across its interior, consists of multiple defensive rings; a substantial earthen bank encircles the central area, followed by a fosse (defensive ditch), then a smaller outer bank and another fosse. Archaeological surveys have even detected traces of what appears to be an additional bank beyond the outermost ditch, suggesting this was once a formidable defensive structure with three concentric rings of protection.

Today, nature has largely reclaimed this historic site. Trees and bushes have overtaken the earthen banks, whilst the outer defences have become so overgrown that they’re nearly invisible except along the western side where their outline can still be traced. The fort’s interior sits slightly elevated above the surrounding fields, a subtle reminder of the engineering work that went into its construction centuries ago. This raised platform would have provided both practical drainage in the marshy terrain and a strategic advantage for those who lived within.

Ringforts like this one, known locally as raths, were the homesteads of farming families during the early medieval period, roughly from 500 to 1200 AD. The multiple banks and ditches at Lissacholly suggest this was home to a family of considerable status; the more elaborate the defences, the wealthier and more important the inhabitants. Its location in wetland, whilst challenging for modern visitors, would have offered natural protection from raiders and provided access to diverse resources including fish, waterfowl, and the rich grazing land that often borders boggy areas.
