It was the first lighthouse ever built, between 297 and 283 BC, and served for almost 1500 years successively for the Greeks, Romans, Byzantines and Arabs. According to Arab and European travel accounts, the lighthouse was in service until about 1375 when a severe earthquake plunged the top half of the light installation into the sea.
