The island of Sulawesi (Indonesian: Celebes) is one of the four Greater Sunda Islands of Indonesia. Located between the Moluccas archipelago and the large island of Borneo, it consists of several long peninsulas extending from a mountainous center. It is divided into six provinces, with Makassar (in the south) and Manado (in the north) being its main cities and transportation hubs. It is famous for its coral reefs and diving sites, such as Bunaken National Park, the Togian Islands, and Wakatobi National Park. Its largest city is Makassar, home to Fort Rotterdam, a former Dutch fort that now houses two museums. Outside Makassar, Leang-Leang Historical Park preserves prehistoric cave paintings.
