Pulau Blakang Mati

The former name of Sentosa was Pulau Blakang Mati, where Blakang Mati means “behind the dead” in Malay.

No one knows exactly how the name of the island came about, but there were many legends about its origin. According to one version, the island was once a place of piracy and bloodshed in the past. The victims of the murders haunted the island so much that it was given this not-so-auspicious name. Another account was that the island was located “behind” Pulau Brani, which was the burial ground of many ancient Malay warriors.

Nevertheless, Pulau Blakang Mati was renamed as Sentosa (which means “isle of tranquility”) in 1972. With the island becoming a favourite beach resort among Singaporeans and the tourists, the unhappy legends were soon forgotten.
