drumena cashel and souterain

Drumena is an irregularly shaped stone fort or cashel measuring 132 ft by 108 ft, and with walls 9-12 ft thick (which were partially re-built in 1925-26). The original entrance was probably on the east side, and a confused jumble of stones in the interior may once have formed the foundations of a house. Also inside the cashel is an easily accessible T-shaped souterrain which reaches a maximum height of 7 feet. The whole complex is likely to date from the Early Christian period.
