The central cairn was one focus of the excavations conducted at Rogem Hiri and was found to postdate the ring constructions.  The tomb was most likely constructed in the Late Bronze Age within the existing Early Bronze Age rings (7) .  It contained an entrance chamber, a dromos, which was aligned with the northeast entrance of the site, and a burial chamber in the center.  No burial was discovered in the chamber as it had been looted, but beneath the floor, lying directly on bedrock, was a huge uncut basalt slab also aligned with the northeast entrance.  The cairn was built from the inside out (8) as a semicorbelled dome (9) , and consisted of three terraces or levels which gave the structure the appearance of a tiered cone.  The entire cairn was off center from the surrounding rings, enforcing the concept that its construction was not part of the original structural conception.
