North of Preveza is a sandy beach that stretches for 25 km, making it the longest in Europe. Its name, Monolithi, comes from a rock that once protruded from the surface of the sea, approximately ten meters off the coast. During the Second World War the rock caught the eye of Italian and German soldiers, who decided to entertain themselves by attacking it with mortar rounds. As a result of their practice, the rock disappeared beneath the waves, leaving behind a shoal that does not break the surface of the sea. The name of the beach survives as a reminder of the mighty rock that once stood there; we also have some old black-and-white photographs that preserve its memory.
