Poros port, with its couple of tavernas and bars, connects the island with Kyllini on the Peloponnese area of mainland Greece via regular year-round ferry service.
[3] Separated from Poros port by a small hillock lies the shingle town beach, backed by a taverna-fringed square and main services: bank, chemist (pharmacy), doctor's surgery, post office, police station and local shops.
More tavernas and bars lie along the award-winning 'Blue Flag' beach, Aragia, separated from the centre of Poros by the Vohinas river which, although used as a car park in summer, can be a raging torrent in winter.
Interesting finds brought to light - tools made of stone and bone, figurines, pottery - tell us a good deal about the use of the cave in prehistoric and historic times.
The area around Poros was certainly inhabited during the period when Mycenae was all-powerful, evidenced by the discovery, in 1991, of a tholos (Beehive tomb) in nearby Tzanata.
The size of the tomb, the nature of the burial offerings found there and its well chosen position point to the existence of an important Mycenaean town in the vicinity.
Successive occupiers - Romans, Franks, Venetians, Italians, French, Russians, Turks (very briefly) and finally the British (until 1834) - controlled Cephalonia and, under the governorship of Sir Charles Napier, settlers from Malta were re-located into the fertile area around Poros in an attempt to implement a model agricultural settlement and re-populate this part of the island.
