This monument is located at the back of the Westerkerk and consists of three pink equilateral triangles, one embedded in the pavement, another raised and a third pointing towards Keizersgracht. Seen from the sky these three triangles come together making another triangle also much larger equilateral. It was inaugurated in 1987 and pays tribute to homosexuals, gays and lesbians who have been persecuted because of their sexual orientation, adopting the symbol of the pink triangle, which was the hallmark that homosexuals detained in the Nazi concentration camps should wear. The orientation of the three vertices of the larger triangle, formed by the virtual union of the other three, is also symbolic, pointing, respectively, to Dam Square, to the house of Anna Frank, and to the headquarters of COC Nederland, the LGBT organization oldest in the world, which still works today. Visually, the monument is not too flashy; its importance lies in its meaning, framed within the atmosphere of tolerance that is breathed in the city.
