About Us


Founded in 1985, the Gay, Lesbian, Bisexual, Transgender (GLBT) Historical Society is recognized internationally as a leader in the field of LGBTQ public history. Our operations are centered around two sites: our GLBT Historical Society Museum, located since 2011 in the heart of San Francisco’s Castro neighborhood; and our Dr. John P. De Cecco Archives and Research Center, open to researchers in the Mid-Market district.

Our mission is to collect, preserve, exhibit and make accessible to the public materials and knowledge to support and promote understanding of LGBTQ history, culture and arts in all their diversity.

Make sure to follow us on Facebook, Instagram and Twitter for all of the latest updates and for sneak peeks into our over 900 archival collections.


We are making LGBT historical materials available online around the clock, so you can experience history from home! Click on the links below to learn more about our online collections and exhibitions, upcoming events and more.
