The museum was built in 1970 by the architect Paul Mylonas and opened to the public in 1978.
It contains collections of finds from the sanctuary of Poseidon, the sanctuary of Palaimon, the Hellenistic settlement at Rachi, and from the excavations in the area of Isthmia and the ancient harbour of Cenchreai.
