Malta has been inhabited from around 5900 BC, since the arrival of settlers from the island of Sicily. A significant prehistoric Neolithic culture marked by Megalithic structures, which date back to c. 3600 BC, existed on the islands, as evidenced by the temples of Mnajdra, Ggantija and others. The Phoenicians colonised Malta between 800–700 BC, bringing their Semitic language and culture.
