Sapientza, one of the three Oinoussai Islands, is a low island with an area of 9 square kilometres, its highest peak being on its north part, Foveri, at a height of 219 m. The slopes of the island climb up in lush greenery, and the crystal clear waters of the sea, have a unique exotic colour. The mystery of the island becomes stronger because its real historical development is virtually unknown, so each visitor can be a potential explorer. Sapientza has been the favourite docking place for every fleet that had business with the cities of Methoni and Koroni, these important cities of the Mediterranean during the whole span of the Middle Ages. The ships that usually sailed near the coast of the island frequently crashed on its rocky coast resulting in the discovery of many important shipwrecks from all the historical periods.

 

At the southeast part of Sapientza island there are two islets, called Duo Adelfia ('Two Borthers"). To their southeast, the Oinnousai Pit is located, an underwater abyss that reaches to the deepest part of the Mediterranean, at 5.121 m., where research for the "NESTOR" experiment is conducted and has to do with neutrinos and the past of the universe. Many Greek and international institutions contribute to this effort.

 

In front of the port of Pylos is the island of Sfaktiria. South of Sfaktiria is located the small island of Pylos also known as Tsichli-Baba or Fanari. There, in 1890 the French Republic built a monument for the French who were killed in the Battle of Navarino. Between Tsichli-Baba and Sfaktiria are the Koutsoynes, the two rocks sharp reminiscent which are reminding the moment when Aris, in April 26, 1825 during the siege of Niokastro by Ibrahim, on the ship of Admiral Tsamadou, managed to escape in the night through this passage, after causing huge damage to the Turkish - Egyptian fleet.

 

On the south side of Sfakteria, in 1959 was built a monument for the Greek who were killed in the battle of Sfaktiria which has over it the names of Tsamadou, Sahinis and Anagnostara. Further in the north is the tomb of Paul Bonaparte, Napoleon’s nephew, who was killed in 1827 by the detonation of a weapon, on the warship Hellas. His corps was buried, eventually, in Sfaktiria in 1832 after having remained for five years in a barrel of rum. North, up the coast, is the monument of count Santarosa, a philellenist, who was killed in the battle of Sfaktiria on April 26, 1825. The monument was built in 1926 by the Italian state.

 

Further on the north is the monument of the Russians killed in the Battle of Navarino, which was constructed in 1872 by Queen Olga and was completed in 1960. Next to it is the Russian style chapel of Ag.Nikolaos, a donation of the emigrants from the town Petrozavontse. In its northern part, Sfaktiria has the pass of Sykia, a sea lane with a maximum width of 150m which is no longer the entrance to the harbor, since the Turks sank their destroyed ships that were left there from the naval battle of Nafpakto in 1571.

 

Inside the port there is the small Island of Chelonaki. On this island is the monument of the British killed in the battle of Navarino. It was built by the Greek state.
