Full of neoclassical mansions and whitewashed alleys, the town of Poros is amphitheatrically built above the harbour and is ideal for walks. Stroll along the cosmopolitan waterfront with its picturesque shops, bars for refreshing cocktails just before sunset overlooking the sailing boats bobbing in the bay.
Visit the majestic Temple of Poseidon in Palatia (6th century BC) in the north of the island. The Doric moat that you will see in the central Temple, the galleries of the Agora and the bouleuterion still stand, inviting the visitor to a primordial ritual. This is the place where Demosthenes breathed his last, drinking hemlock to escape the hands of Macedonian king Philip.
Explore the ruins of the Russian Naval Base, located in a small harbor in the northwest of the island. The Russian fleet was using the bay as its supply station since 1834, and its stone-built buildings bear the official designation of "historical listed sites " by the Ministry of Culture.
It is worth visiting the famous Clock Tower of Poros at the highest point of the hill, which has been the most famous attraction of the island since the beginning of the 20th century. The view to the harbour and the coast of the Peloponnese is panoramic, while the 146 steps leading to the clock tower are a challenge for every visitor.
Do not forget to visit the Archaeological Museum, with findings from the excavations at the Temple of Poseidon and ancient Troezen. Don’t miss the plaster cast with the text of the Athenian resolution on the Persian invasion, proposed by Themistocles in 480 BC. Also, the pedestal of the bronze statue of the Roman Emperor Marcus Aurelius, which demonstrates the geographical importance of the island in the Roman era.
Walk in front of the neoclassical “Galini” mansion, which the locals call the "Red House". It is a legendary residence that hosted important figures of literature and arts since the 19th century, such as Seferis, Karagatsis, Chagall, Miller and Greta Garbo, the Hollywood diva.
Stop at the Folklore Museum to see an unparalleled collection of everyday objects, clothing, furniture, and agricultural tools that represent the living conditions of the inhabitants of the island over the past three centuries.
Finally, it’s worth visiting the metropolitan church of Agios Georgios, with the impressive frescoes by the excellent painter Konstantinos Parthenis, as well as the permanent shell exhibition at the Municipal Library.
