The Treasury of Atreus is an ancient tomb in Mycenae, Greece. The tomb is in the architectural style of a beehive, or "tholos." The tomb resembles a large version of a brick oven. The Treasury of Atreus was discovered by German archaeologist Heinrich Schliemann, and it was Schliemann who gave the tomb its name.
The enormous Treasury of Atreus is situated on the side of Panagitsa Hill in Mycenae. The tomb's architectural design and the engineering method used for the structural support is similar to other tombs made during the Bronze Age in the Mycenaean World. However, the extravagant detailing and size make the Treasury of Atreus stand out among the other tombs discovered in the area. The shape of the Treasury of Atreus is also in the style of a monument, which leads archaeologists to believe that it is the tomb of a sovereign from an unknown era.
Another unique feature of the Treasury of Atreus is its luxurious detailing compared to other Bronze Age structures. For instance, porphyry and alabaster are incorporated into the tomb's interior spaces.
