From 1836 to 1931 the island was used as a leper colony and in the 20th century it became infamous as a gaol for political prisoners under apartheid.

Notable amongst these were Nelson Mandela, Walter Sisulu, Tokyo Sexwale, Govan Mbeki, Dennis Brutus and Robert Sobukwe.

During the time that the island was a prison, security was very tight and it was off limits to almost all civilians, including fishermen.
