This tomb dates from the 4th century BC. There are five stone coffins (two on either side of the ante room, three in the main room) inside and the chamber has a false (corbelled) vault. Some Doric architectural blocks from the superstructure are arranged in the slope. From authoritative site: "It is not known whose tomb this was. On the other hand its plan and architectural organization relates it clearly to the Hekatomnid type of Mausolea and it would not be surprizing if this structure was built by and for a member of this family."
