Cape Town was home to many leaders of the anti-apartheid movement. On Robben Island, a former penitentiary island from the city, many famous political prisoners were held for years. In one of the most famous moments marking the end of apartheid, Nelson Mandela made his first public speech since his imprisonment, from the balcony of Cape Town City Hall hours after being released on 11 February 1990. His speech heralded the beginning of a new era for the country, and the first democratic election, was held four years later, on 27 April 1994. Nobel Square in the Victoria & Alfred Waterfront features statues of South Africa's four Nobel Peace Prize winners: Albert Luthuli, Desmond Tutu, F. W. de Klerk and Nelson Mandela.
