The Presidio of San Francisco houses one of the finest collections of military architecture in the United States. It is also the nation’s largest and most ambitious historic preservation project.

Approximately 469 historic buildings contribute to the Presidio’s status as a National Historic Landmark District. National Historic Landmarks are significant historic places selected by the federal government because of their exceptional ability to illustrate America’s heritage. The Presidio’s landscapes such as the historic forest as well as other features also contribute to landmark status.

The Presidio’s historic buildings were constructed primarily by the U.S. Army from the Civil War through World War II. Building types include former officers’ quarters, barracks, warehouses, hangars, medical facilities, and administrative buildings (view Presidio Architectural Styles). Entire streetscapes of historic buildings are intact, as well as individual buildings that are important in their own right. The Presidio’s landmark status is not based on individual buildings but rather on the entire collection of structures representing many layers of history.

The Trust and its partners are rehabilitating the park’s historic homes, batteries, barracks, office buildings, warehouses, and facilities according to the highest federal standards.
