The ruins of the Delphi gymnasium were found on the archaeological site of Delphi between the Kastalia Fountain and the Athens Pronaia temple. It was built on two levels with the upper level housing the fore (which length is apparent after the latest excavation), an arcade 7 meters wide and 178.3 meters long where athletes practiced running in bad weather. In fact, it owes its name to the fact that it had to be scraped to level it out.
On the lower level there is a ring, with a square courtyard and galleries, where boxing and wrestling training took place. To the west of the ring is a preserved circular pool 10 meters in diameter and 1.8 meters deep, one of the characteristics attributed to Greek baths.
During the Hellenistic period the gymnasium was turned into a place where citizens developed their spiritual culture and philosophers, poets, sophists and rhetors gave their speeches. Over the centuries a Byzantine monastery was erected on the site.
