- LEFTERIS Reef
A small rock with a huge history behind it. The reef has a length from north to south about 180 meters and width 80m. According to Irodotos during the invasion of the Persians in Greece, at least three of the Persian galleys of king Xerxes ran into the reef and sank. After that event King Xerxes ordered the Persians to carry blocks of stone weight of 700-1.200 pounds and built on top of the reef a stone column to highlight the risk and to ensure safe navigation. It is considered the most ancient construction known until today (2,5 centuries prior to the Lighthouse of Alexandria), segments of which were pulled up with the help of the divers in 1928. Diving around the reef offer a unique experience. Another impressive route exists far beyond the two shipwrecks. Vertical walls are lost in blue, meadow countless corals and vibrant underwater life compose a fascinating underwater scenery able to move and excite even the most experienced diver.
