1) Poros Island

Poros is a small Greek island-pair in the southern part of the Saronic Gulf, at a distance about 58 km (31 nautical miles) south from Piraeus and separated from the Peloponnese by a 200 m wide sea channel, with the town of Galatas on the mainland across the strait. The town of Poros, with its neoclassical edifices, is built amphitheatrically on the slopes of a hill. Its most famous landmark is a clock tower, built in 1927. The Archaeological Museum of Poros, at Korizis Square, houses findings from the Sanctuary of Poseidon, from ancient Troizen, and from other archaeological sites nearby. In the northern part of the island are the remains of the Sanctuary of Poseidon, the centre of the Kalaureian amphictyony. The exact date it was built is not known, although researchers estimate it to have been around 520 BC. The dimensions of the temple, which is of the Doric order, are 27.4×14.4 m. There are six columns on each short side and twelve on each long side. It was here that Demosthenes, the famous orator, poisoned himself with hemlock in 322 BC fleeing from the Macedonian Governor Antipatros.

It consists of a crescent-shaped harbour, around which is centered a strand of restaurants, shops, markets, and galleries that cater to tourists and locals. Steep stone streets lead up and outwards from the harbor area. Most of the local residences, as well as the hostelries on the island are located on these streets. There are numerous churches and six Orthodox monasteries. Two particularly noteworthy monasteries are Profitis Ilias, founded in the 10th Century, and Ayia Efpraxia. Both are on a hill overlooking the main harbour.
