What is "vaphio"

Vaphio is an ancient site in Laconia, Greece, on the right bank of the Eurotas, some five miles south of Sparta. It is famous for its tholos or " beehive" tomb, excavated in 1889 by Christos Tsountas. This consists of a walled approach, about 97 feet long, leading to a vaulted chamber some 33 feet in diameter, in the floor of which the actual grave was cut.
