This moated site measures 21 metres from north to south and 22 metres from east to west, enclosed by an earthen bank that rises 0.6 metres on the inside and 0.85 metres on the outside. Around this bank runs an external fosse, or defensive ditch, with a base width of 1.6 metres and a depth of 0.25 metres. A single break in the western side of the bank, spanning 3.4 metres, would have served as the original entrance to this medieval enclosure.

Today, the interior of the site remains level but marshy, likely much as it has been for centuries. These moated sites are fascinating remnants of medieval Ireland, typically dating from the 13th to 14th centuries when Anglo-Norman settlers established farmsteads across the countryside. The moat and bank combination provided both drainage for the central platform and a degree of security for the inhabitants, their livestock, and stored goods.

While many such sites once dotted the Irish landscape, particularly in counties like Limerick where Anglo-Norman influence was strong, relatively few survive in recognisable condition. This example at Killeedy North, though waterlogged, preserves the classic rectangular form and defensive features that characterised these medieval homesteads, offering a tangible link to the agricultural and social patterns of medieval rural life in Ireland.
