Isthmia in antiquity was a large Panhellenic sanctuary dedicated primarily to the worship of Poseidon. As a Panhellenic site, its games attracted visitors from across the Greek world every two years. The complexity of the site's history has been corroborated over the past half century through the near-continual fieldwork at the site, beginning in the 1950s.
