Leacanabuaile Fort, in Cahersiveen County Kerry, is one of the best examples of the interior of a round stone fort in Ireland. Its walls are about 3m thick and have been reconstructed to a height of about 1.5m. Inside are three stone beehive houses, the square house in the middle is apparently of a later date. There is also a souterrain, originally an escape area and a place of refuge and storage, as well as the remains of a rotary quern for grinding corn.
Leacanabuaile Fort is one of very few of these forts to be excavated, this was done in 1939/40. Objects found include iron, bone, bronze, lead and stones, dating from the 9th or 10th century.
