The Pink Triangle Park is a triangle-shaped mini-park located in the Castro District of San Francisco, California. The park is less than 4,000 square feet and faces Market Street with 17th Street to its back. The park sits directly above the Castro Street Station of Muni Metro, across from Harvey Milk Plaza. It is the first permanent, free-standing memorial in America dedicated to the thousands of persecuted homosexuals in Nazi Germany during the Holocaust of World War II. Fifteen triangular granite pylons, or columns, are dedicated to the thousands of homosexual, bisexual, and transgender victims that were killed during Hitler's Nazi regime.
