Mar Barracks treasure island SF cali

Mar Barracks, located on Treasure Island in San Francisco, California, was a significant military installation established during the late 1930s as part of the island’s transformation for the Golden Gate International Exposition. During World War II, the facility became a strategic U.S. Navy barracks and training center, supporting personnel movement and logistics for operations in the Pacific Theater. The barracks housed thousands of sailors and served as a key transit and processing point throughout the war and into the early Cold War era. After decades of service, Mar Barracks and the broader Treasure Island Naval Station were decommissioned in the 1990s, with the site transitioning to civilian use.
