This sub-rectangular earthwork measures roughly 27.4 metres east to west and 22 metres north to south, enclosed by a low earthen bank that rises just 35 centimetres above the surrounding ground. The defensive layout includes an external fosse, or ditch, running along the eastern and southern sides, cut to a depth of about 30 centimetres. A second, more substantial bank standing 60 centimetres high runs outside the fosse on the eastern side, creating a double line of defence typical of medieval fortified sites.

The site at Kilmore represents a type of medieval settlement that became common in Ireland during the Anglo-Norman period, particularly from the 13th to 15th centuries. These moated sites typically served as fortified farmsteads for colonists or prosperous farmers, offering protection whilst allowing agricultural activities to continue in the surrounding landscape. The rectangular shape and modest defensive features suggest this was likely a working farm rather than a military stronghold, though the double banking on the eastern approach indicates concerns about security from that direction.

Today, the interior space shows signs of later agricultural use, with field clearance stones dumped inside the enclosure and partially filling the northern section of the fosse. Despite these modifications, the earthworks remain clearly visible, preserving the footprint of what was once someone’s protected homestead. The site forms part of the broader medieval landscape of West Cork, documented in the Archaeological Inventory of County Cork and continuing to offer insights into how people lived and defended themselves in medieval rural Ireland.
