A round cairn, roughly 22m in diameter and 3.5m high, covers a well-preserved cruciform passage tomb opening to the northwest. The tomb itself consists of a 4.5m long passage leading to a tall chamber 1.4m long x 1.9m wide. There are two opposed side-chambers and an end-chamber. The tomb is constructed of orthostats with dry-wall infill which support a series of lintels, a number of which are now cracked, and oversailing corbels capped by a large flat slab above the main chamber. The orientation of the passage seems to point toward the massive Medb's Cairn on the summit of Knocknarea some 25 km (15.5 miles) away.
