The Tholos of Delphi is among the ancient structures of the Sanctuary of Athena Pronaia in Delphi. The circular temple, a tholos, shares the immediate site with other ancient foundations of the Temple of Athena Pronaia, all located less than a mile east of the main ruins at Delphi, in the modern Greek regional unit of Phocis. The tholos is part of the Delphi UNESCO World Heritage Site.
