This ringfort at Lisheennacreagh sits on an east-south-east-facing slope in West Cork, and whoever built it raised the interior on the eastern side to create a flat, usable surface within the enclosure. It is a small detail, but it says something about the seriousness of the undertaking.

Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically serving as enclosed farmsteads for a family and their livestock. They are defined by a raised earthen bank, and often by a fosse, which is a ditch dug around the outside to provide both the material for the bank and an additional barrier. The example at Lisheennacreagh is a well-preserved specimen of the type. Its roughly circular enclosure measures just under 46 metres north to south and nearly 49 metres east to west. The surrounding bank still stands to a height of 3.25 metres, which is substantial, and the external fosse, running from the western side around to the south, reaches a depth of 1.8 metres. A gap of about 3.4 metres in the bank to the south-south-east marks what would have been the original entrance. The site sits in pasture today, grazed rather than ploughed, which has helped it survive in reasonable condition.
