The National Monuments Service's description

On a flat low-lying landscape within a golf-course. Described (de Valera and O 'Nuallain 1972, 33-4) as a gallery (dims 8.5m E-W; 1-1.7m N-S) with seven side-stones on the N and ten on the S sides, and with one lintel at the E end. The W end is separated by a septal stone from a portico (dims 1.5m x c. 1.5m) which has two facade stones to the N. It was within a trapezoidal cairn or mound (dims c. 10m E-W; c. 2.5m N-S at E to c. 7.5m N-S at W) defined by kerbstones at N and S. It is now visible as a circular, rounded and grass-covered mound (diam. c. 24m; H 1.6-2m) with the capstone of the gallery just visible on its summit. Rath (RO006-172----) is c. 80m to the SW.
