| | Presidio of San Francisco (National Park Service) |
 | | The Presidio served as a military post under the flags of Spain (1776-1822), Mexico (1822-48), and the United States (1848-1994). |
 | | The Presidio Trust is a special public-private governmental agency tasked with managing most of the buildings of the Presidio and making the park financially self-sufficient by 2013. |
 | | Within its boundaries are more than 500 historic buildings, a collection of coastal defense fortifications, a national cemetery, an historic airfield, a saltwater marsh, forests, beaches, native plant habitats, coastal bluffs, miles of hiking and biking, and some of the most spectacular vistas in the world. |
