It is the first permanent, free-standing memorial in America to the thousands of persecuted homosexuals in Nazi Germany during the Holocaust. Fifteen triangular granite columns—one for every 1,000 gay, lesbian, bisexual, and transgender persons estimated to have been killed during the Holocaust—surround the a pink-quartz-filled triangle in the center of the park. The triangle theme recalls the Nazis forcing gay men to wear pink triangles sewn to their clothes as an identifier and badge of shame. Pink Triangle Park was dedicated on 10 December 2001 by the Eureka Valley Promotion Association. According to the neighborhood group that maintains the space, the Pink Triangle Park serves as "a physical reminder of how the persecution of any individual or single group of people damages all humanity."
