Isthmia (sanctuary)

Isthmia is an ancient sanctuary on the Isthmus of Corinth in the northeastern Peloponnese, best known as the location of the Panhellenic Isthmian Games. The site centers on the sanctuary of Poseidon and includes remains spanning the Archaic, Classical and Roman periods.

Surviving features include temple foundations and architectural fragments of the sanctuary, a Roman bath complex, and the remains of a stadium used for athletic contests. An archaeological museum at the site displays pottery, inscriptions and other finds recovered during excavations.

The sanctuary hosted the Isthmian Games, a major festival and athletic series in classical Greece that complemented the other Panhellenic games. The site continued in use into the Roman period and was subject to archaeological excavation in the 20th century.

Isthmia sits beside the narrow land bridge that connects the Peloponnese to mainland Greece, close to the modern village of Isthmia and north of the city of Corinth. It is readily accessible by road from nearby towns and from the Corinth Canal area.

• Museum on-site: Excavated archaeological remains and an on-site museum make the site easy to explore on foot; the museum concentrates finds from the sanctuary and nearby excavations.
• Combine with Corinth: The sanctuary lies close to the modern Isthmus and is easily combined with visits to Corinth and the nearby canal for a single-day outing from the Peloponnese.
