Jurong Island is an artificial island located to the southwest of the main island of Singapore, off Jurong Industrial Estate. It was formed from the amalgamation of seven offshore islands, the islands of Pulau Ayer Chawan, Pulau Ayer Merbau, Pulau Merlimau, Pulau Pesek, Pulau Pesek Kechil (also called Terumbu Pesek), Pulau Sakra (which was a previous merger of Pulau Sakra and Pulau Bakau), Pulau Seraya, Pulau Meskol, Pulau Mesemut Laut, Pulau Mesemut Darat and Anak Pulau. This was done through land reclamation. Land reclamation on Jurong Island was completed on September 24, 2009, 20 years earlier than scheduled.
