About Castro
The Castro is San Francisco's historic LGBTQ+ neighborhood, anchored by Castro Street and Market Street, and globally recognized as one of the most important centers of gay culture and activism in the world. It hosts the annual Pride march staging area, the Castro Theatre (a 1922 movie palace), the GLBT Historical Society Museum, and countless bars, cafes, and landmark businesses. The population is predominantly gay, middle-class to affluent, and ranges from longtime residents to younger professionals. Harvey Milk's camera shop and political home were here, and the neighborhood retains its identity as a political and cultural anchor despite rising rents.
