Eureka Valley is a neighborhood in San Francisco, primarily a quiet residential neighborhood but boasts one of the most visited sub-neighborhoods, The Castro.
It is an affluent neighborhood popular with family and the LGBT community. The rainbow flag, signifying LGBT pride, can be seen displayed throughout the area. It was initially a working-class Irish neighborhood until a combination of factory jobs loss and the migration of gays into The Castro radically changed the neighborhood in the 1960s. In 1977, this district elected the first openly gay politician (Harvey Milk) to public office (San Francisco Board of Supervisors).
