Indonesia has been independent since 1945, after having been the Dutch East Indies for more than 350 years. It is a huge country, stretching along both sides of the Equator for more than 46 degrees of longitude (roughly 5100 km or 3200 miles). Comprised of some 17,000 islands (more than 6000 inhabited islands), it has hundreds of major aids to navigation. This page includes the lighthouses of Sulawesi (Celebes), a major island in the northern part of the country.
Shaped like an artistically drawn letter K, Sulawesi consists mostly of four narrow peninsulas. The Makassar Strait separates Sulawesi from Kalimantan (Borneo) to the west. The Celebes Sea is north of the island, the Banda Sea is to the east and southeast, and the Flores Sea is on the south. Makassar, also called Ujung Pandang, is the major port.
The Indonesian word for a lighthouse is mercusuar. The phrase menara suar, which includes the Arabic word menara, is sometimes used instead. Pulauis an island and karang is a reef.
