Sulawesi (), also 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 Southeast 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. Etymology The name Sulawesi possibly comes from the words sula ("island") and besi ("iron") and may refer to the historical export of iron from the rich Lake Matano iron deposits. The name came into common use in English following Indonesian independence. The name Celebes was originally given to the island by Portuguese explorers. While its direct translation is unclear, it might be considered a Portuguese rendering of the native name "Sulawesi". Geography Sulawesi is the world's eleventh-largest island, covering an area of . The central part of the island is ruggedly mountainous, such that the island's peninsulas have traditionally been remote from each other, with better connections by sea than by road. The three bays that divide Sulawesi's peninsulas are, from north to south, the Tomini, the Tolo and the Boni. These separate the Minahassa or Northern Peninsula, the East Peninsula, the Southeast Peninsula and the South Peninsula. The Strait of Makassar runs along the western side of the island. The island is surrounded by Borneo to the west, by the Philippines to the north, by Maluku to the east, and by Flores and Timor to the south. Minor islands The Selayar Islands make up a peninsula stretching southwards from Southwest Sulawesi into the Flores Sea are administratively part of Sulawesi. The Sangihe Islands and Talaud Islands stretch northward from the northeastern tip of Sulawesi, while Buton Island and its neighbors lie off its southeast peninsula, the Togian Islands are in the Gulf of Tomini, and Peleng Island and Banggai Islands form a cluster between Sulawesi and Maluku.
