| Across from the treasuries stands the Tholos, a circular,
marble structure. Twenty Doric columns topped the base of three steps.
The metopes depicted the Battle of the Amazons and the Battle of the
Centaurs, while Corinthian half-columns decorated the cella's interior.|
The Tholos was built in the early 4th century, possibly by Theodoros of
Phokaia. Three columns have been restored, along with replicas of the
cornice, metopes, epistyle, triglyphs, and some of the guttering of the
roof. While the purpose of the building is still unclear, some believe it
was dedicated to time related deities.
