The Homomonument is a memorial in the centre of Amsterdam, the capital of the Netherlands. It commemorates all gay men and lesbians who have been subjected to persecution because of their homosexuality. Opened on September 5, 1987, it takes the form of three large pink triangles made of granite, set into the ground so as to form a larger triangle, on the bank of the Keizersgracht canal, near the historic Westerkerk church. The Homomonument was designed to "inspire and support lesbians and gays in their struggle against denial, oppression and discrimination." It was the first monument in the world to commemorate gays and lesbians who were killed by the Nazis.
Later, similar monuments were realised in a number of cities all around the world.
During the Netherlands’ annual Remembrance Day ceremony on May 4, wreaths are laid on the monument to commemorate LGBT victims of persecution. On May 5, Liberation Day, the monument becomes the site of a street party.
