Jurong Island is located to the southwest of the main island of Singapore. It was formed from the amalgamation of several offshore islands, chiefly the seven main islands of Pulau Ayer Chawan, Pulau Ayer Merbau, Pulau Merlimau, Pulau Pesek, Pulau Pesek Kechil, Pulau Sakra, and Pulau Seraya, but also Pulau Meskol, Pulau Mesemut Laut, Pulau Mesemut Darat and Anak Pulau. This was done through Singapore's land reclamation efforts. Land reclamation on Jurong Island was completed on 25 September 2009, 20 years earlier than scheduled. Pulau Buaya was joined to Jurong Island via reclamation in 2010. Jurong Island forms a land area of about 32 km2 (12 sq mi) from an initial area of less than 10 km2 (4 sq mi).
