Sulawesi, formerly known as Celebes is an island in Indonesia. One of the four Greater Sunda Islands, and the world’s eleventh-largest island, it is situated east of Borneo, west of the Maluku Islands, and south of Mindanao and the Sulu Archipelago. Within Indonesia, only Sumatra, Borneo and Papua are larger in territory, and only Java and Sumatra have larger populations. The landmass of Sulawesi includes four peninsulas: the northern Minahasa Peninsula; the East Peninsula; the South Peninsula; and the South-east Peninsula. Three gulfs separate these peninsulas: the Gulf of Tomini between the northern Minahasa and East peninsulas; the Tolo Gulf between the East and Southeast peninsulas; and the Bone Gulf between the South and Southeast peninsulas. The Strait of Makassar runs along the western side of the island and separates the island from Borneo.
