Malacca (Malay: Melaka), officially the Historic State of Malacca (Malay: Melaka Negeri Bersejarah), is a state in Malaysia located in the southern region of the Malay Peninsula, facing the Strait of Malacca. The state is bordered by Negeri Sembilan to the north and west and Johor to the south. The exclave of Tanjung Tuan also borders Negeri Sembilan to the north. Its capital is Malacca City, which has been listed as a UNESCO World Heritage Site since 7 July 2008. Malacca has diverse tropical rainforests and experiences an equatorial climate. Situated immediately south of the Titiwangsa Mountains, the state is mostly level and dotted with inselbergs, with Bukit Gapis as the highest point. Although it was the location of one of the earliest Malay sultanates, namely the Malacca Sultanate, the local monarchy was abolished when the Portuguese conquered it in 1511. The head of state is the Yang di-Pertua Negeri or Governor, rather than a sultan. Malacca is noted for its unique history and it is one of the major tourist destinations in Malaysia. With a highly strategic state position for international trade routes, Malacca was once a well-known international trade centre in the East.
