"While the function of the Tholos is not completely clear, there are some theories about suggested usage. One possibility is that it was a chthonic cult dedicated to a god or local hero, similar to the Tholos at Epidauros. Another suggestion is that the Tholos was a circular treasury in which statues were kept, much like the Philippeion at Olympia."
