Myth has it that this richly verdant island was the birthplace of Theseus. In the 7th century BC Poros, then called Kalaureia, was the seat of an amphictyony of seven cities. During the Greek War of Independence (1821) the inhabitants of Poros joined forces with those of Spetses and Hydra, putting their ships in the service of the Struggle.

The delightful little town of Poros is the island’s capital and port. To the east of the harbour is the richly wooded islet of Bourtzi with a small castle built for its protection in 1827. Housed in the Poros Archaeological Museum, tel. (22980) 23.276, are important finds from the island and ancient Troezen. Some 5 km NE of the town are the remains of the sanctuary of Poseidon, with a 6th century BC temple in the Doric order. The area is called Palatia by the locals and has a stunning view.

Near the harbour, on the S coast of Poros, is enchanting Askeli with superb sea and dense pine woods. On an eminence beside the shore is the Zoodochos Pigi Kalavrias Monastery. Three km NW of Poros are Mikro and Megalo Neorio, beautiful sandy beaches with pine trees down to the water’s edge.

There are plenty of opportunities for taking excursions from Poros to the opposite coasts of the Argolid, crossing the strait by sea taxi or ferryboat. Directly opposite the harbour of Poros is the Peloponnesian town of Galata, set in the midst of greenery, and further S is the idyllic Lemonodasos (lit. Lemon Wood). There are fuel and water supply facilities for boats in Poros harbour. Information, Poros Harbour Office, tel. (22980) 22.274, (22980) 22.224.

In early July Naval Week is organized, with cultural events and exhibitions associated with the island’s nautical history.
