The Mycenaean tholos tomb at Acharnai (or the so called tholos tomb of Menidi) was excavated by the German Archaelogical Institute in 1879, under the supervision of the Greek Government’ s Ephorate of Antiquities. It’s the best preserved tholos tomb in Attica. The tholos tomb at Acharnai is the latest in Attica, dating to the 14th-13th cent. B.C. It was built to receive the members of the elite families of the region.
