The Treasury of Atreus or Tomb of Agamemnon is an impressive "tholos" tomb on the Panagitsa Hill at Mycenae, Greece, constructed during the Bronze Age around 1250 BCE. The lintel stone above the doorway weighs 120 tons, the largest in the world. Ancient traveller Pausanias visited Mycenae in the second century and called it Tresuary of Atreus. However, the association with Agamemnon or Atreus (Atreus is a king of Mycene, son of Pelops and Hippodamia, and father of Agamemnon and Menelaus) is purely speculative and no archeological/epigraphical proof has been found.
The tomb perhaps held the remains of the sovereign who completed the reconstruction of the fortress or one of his successors. The grave is in the style of the other tholoi of the Mycenaean World, of which there are nine in total around the citadel of Mycenae and five more in the Argolid. However, in its monumental shape and grandeur it is one of the most impressive monuments surviving from Mycenaean Greece.
