Golden Gate National Parks Conservancy

You are standing at the heart of what was once a critical military nerve center, now repurposed as a hub for park preservation. The building you see, known as Building Two Hundred and One, served as an army hospital during the Civil War era. Today, it functions as the headquarters for the National Park Service and the Golden Gate National Parks Conservancy. This organization works as a nonprofit partner to support the stewardship of thousands of acres of parkland across the region. They coordinate projects ranging from habitat restoration to the maintenance of historic structures like those surrounding you at Fort Mason.
