This memorial is located in Green Park, in the inner city suburb of Darlinghurst. The Sydney Gay and Lesbian Holocaust Memorial was designed by Russell Rodrigo and Jennifer Gamble and opened in 2001. In the form of a pink triangle and black poles, it commemorates the gay men and lesbian women who were murdered, tortured or persecuted because of their sexuality, by the Nazis during World War II. The pink triangle was one of the Nazi concentration camp badges, used to identify male prisoners who were sent there because of their homosexuality. Green Park is near the Sydney Jewish Museum and Darlinghurst is considered the heart of Sydney's gay and lesbian population.
