This is a circular stone ringfort (caiseal) of internal diameter 20 m (66 ft) with outer walls over 2 m (6 ft 7 in) high and 3 m (9.8 ft) thick accessible by stairways.
It is built of drystone with gaps filled in with rubble.

In the interior are a large round house and a smaller rectangular house; archaeology has shown that these were preceded by wooden buildings.
A souterrain was located in the circular house.

The entrance has a stone-lined passage similar to that at Staigue stone fort.
