Sulawesi, formerly known as Celebes, is a uniquely shaped island in central Indonesia, renowned for its rich biodiversity and cultural diversity. The island's K-shaped form comprises four peninsulas, surrounded by the Celebes and Banda Seas, and features a tropical climate with distinct wet and dry seasons. As part of the Wallacea region, Sulawesi hosts numerous endemic species, such as the anoa, babirusa, and tarsier, alongside vibrant marine life ideal for diving. The island's diverse ethnic groups, including the Bugis, Makassarese, Toraja, and Minahasa, each contribute to its rich cultural tapestry, with the Toraja people particularly noted for their elaborate funeral rites and unique architecture. Economically, Sulawesi relies on agriculture, producing rice, cocoa, coffee, and spices, while also engaging in significant nickel mining. Tourism thrives on its natural attractions, like Tana Toraja's mountains and Bunaken National Park's coral reefs, as well as its cultural sites. However, the island faces challenges such as environmental degradation and the need for improved infrastructure to support sustainable development.
