|Notes:||Before its excavation in 1934, the cairn was a grass-grown mound measurirg 19m by 9.7m. |
Accessed by a 4.1m long entrance passage, the chamber measures 7.1 m long, 1.6 to 1.8 m wide, and is divided into three main compartments by upright slabs.
Remains of at least 29 human skeletons were on the floor of the passage and chamber, mostly in the two parts of the inner compartment where the skulls were arranged along the base of the walls. The bones were mostly broken, none were articulated, and were mixed with animal bones in a similar condition.
