The Archaeological Museum of Poros, located on Koryzis Square in Poros Town, offers a fascinating look at the island’s long history and its ties to the wider Saronic Gulf region. Though small, the museum’s well‑curated exhibits cover finds from Mycenaean Troezen, ancient Kalaureia (Poros), Methana, and surrounding areas, giving visitors context for the island’s Sanctuary of Poseidon and its role in the Calaurian League.

Key displays include funerary steles, ceramics, inscriptions, and everyday artifacts spanning from the Bronze Age to Roman times. Informative bilingual signage makes it accessible for independent travelers, while its quiet location on the leafy square provides a peaceful break from the busy harborfront.

👉 Pair your visit with a coffee at a nearby square‑side café. Morning is the best time to enjoy the museum without crowds.
