Monolithi
Monolithi is a big sandy beach, in west coast of Preveza Prefecture, Greece. Total length of the beach is 25 km. So, it is the longest sandy beach of European Union,. The name Monolithi comes from Greek roots "Μόνος" + "Λίθος" = "single" + "stone". It was an oversea rock 10X10m, near the coast, until year 1942, when German and Italian soldiers destroyed the rock with mortar fire. A photograph before 1942 is available. Today the rock exists as an undersea reef (-10 cm from the surface).
