Fort Mason, inSan Francisco,California is a formerUnited States Army post located in the northernMarina District, alongsideSan Francisco Bay. Fort Mason served as an Army post for more than 100 years, initially as acoastal defense site[3] and subsequently as a military port facility. DuringWorld War II, it was the principal port for thePacific campaign.[2]
Fort Mason originated as a coastal defense site during theAmerican Civil War. The nucleus of the property was owned byJohn C. Frémont and disputes over compensation by the United States continued into 1968. In 1882 the defenses were named forRichard Barnes Mason, a military governor before statehood. Fort Mason became the headquarters for an Army command that included California and theHawaiian Islands from 1904 to 1907. In 1912 the Army began building a port facility with piers and warehouses to be a home base for ships of theArmy Transport Service serving Alaska, Hawaii, the Philippines and other Pacific Army posts and focus of Army supply for the Pacific.
On 6 May 1932 that port facility was designated theSan Francisco Port of Embarkation, modeled on theNew York Port of Embarkation which supplied U.S. Army forces inWorld War I, to serve the Pacific. Fort Mason then became both the headquarters of the command that was the San Francisco Port of Embarkation and an element of that command. The San Francisco Port of Embarkation assumed responsibility for the Army Transport Service, the San Francisco General Quartermaster Depot at Fort Mason and the Overseas Replacement and Discharge Service atFort McDowell, California. When war came to Europe in 1939 the New York Port of Embarkation was again operating as a port of embarkation on a World War I scale with associated camps and facilities and sub ports soon to be established. On the Pacific only the port at San Francisco was operating. The Army recognized that the relatively small port facility at Fort Mason was inadequate for supporting major wartime operations in the Pacific. In early 1941 the Army began acquiring land and facilities for major expansion inOakland,Seattle and elsewhere in the San Francisco area. By the end of the war Fort Mason and thirteen other facilities composed the San Francisco Port of Embarkation.
The San Francisco Port of Embarkation was the second largest of eight Ports of Embarkation through World War II and was disestablished 1 October 1955. It then became headquarters for the Pacific Transportation Terminal Command.
Today it is part of theGolden Gate National Recreation Area and the site of several cultural facilities. The entire fort area is listed as ahistoric district on theNational Register of Historic Places,[2] with 49 buildings of historic significance, spread over 1,200 acres (490 ha).[4][5] while the lower port area is aNational Historic Landmark District, designated for its role in World War II.
Fort Mason can be split into two distinct areas. The upper area, sometimes called Fort Mason, is situated on a headland and was the site of the original coastal fortifications. The lower area, Fort Mason Center, is situated close to water level to the west of Upper Fort Mason, and is the site of the former military port, with its piers and warehouses. TheMarina Green lies to the west of Fort Mason, whileAquatic Park is to the east.
Black Point, a promontory point of the San Francisco coastline, is situated on the far point of the headland of Fort Mason.[6][7][8] Originally namedPunta Medanos andPunta de San José by the Spanish settlers, it was renamed Black Point after 1849. Black Point was named for the abundance of dark-coloredCalifornia bay laurel trees that grew on the bluff.[7][9][10] The shoreline of Black Point is the last remaining section of original coastline in San Francisco east of the Golden Gate Bridge.[citation needed]
In 1797, the SpanishPresidio of San Francisco constructed theBateria de Yerba Buena atPunta Medanos (now called Black Point) as anartillery battery to provide additional protection to theYerba Buena anchorage. The site was only briefly occupied and was abandoned by 1806.[11][12]
The nucleus of Fort Mason was a private property owned by John C. Frémont, the explorer of the western U.S., who also spearheaded the conquest of California from Mexico, and ran as the first presidential nominee of the extant Republican Party in 1856. As alleged in a 1968 federal lawsuit[13] filed by his descendants over the 70-acre parcel then at issue, Frémont bought a 13.5-acre property in the mid-1850s for $42,000, and then improved it by about $40,000.
Appointed a major general in the Union army at the start of theCivil War, Frémont's repeated serious conflicts with PresidentLincoln led him to resign by late 1862. In 1863, the government seized the property without payment, by executive order of Lincoln, on the grounds it was needed for the war effort. Frémont would again contest the US presidency in 1864, running as the candidate ofRadical Democratic Party, only resigning the effort when Lincoln fired a political enemy in his cabinet as a concession.
The 1968 lawsuit was perhaps the last shot of a century-long legal struggle[14] to obtain compensation for the seized realty. In 1870, the government returned property to 49 parties in the vicinity, but not to Frémont and a few others. At that time, Frémont was still very preoccupied with enough of the vast fortune he had made through gold-mining before the Civil War that the matter was unlikely of concern to him; but by 1872[15] he was in grave financial trouble he would never escape before his death in 1890. Over the years, at least 24 Congressional committees would vote to compensate Frémont, and finally in February 1898 PresidentWilliam McKinley signed a bill directing that the court of claims fix the compensation due. But in 1968 the Frémont heirs complained it had failed to carry out this direction, with John Frémont then recently dead and his widow Jessie over 70 years old.
TheCivil War prompted the construction of several coastal defense batteries located inside theGolden Gate. Initially these defenses were built as temporary wartime structures rather than permanent fortifications and one of these was constructed in 1864 atPoint San Jose, as the location of Upper Fort Mason was then known. A breast-high wall of brick and mounts for six 10-inch (250 mm)Rodman cannons and six 42-pounder guns were built on the site. Excavation in the early 1980s uncovered the well-preserved remains of the western-half of the temporary battery, and it has now been restored to its condition during the Civil War.[16]
The fort was named Fort Mason in 1882, after Richard Barnes Mason, a formermilitary governor of California.[17]
President Grover Cleveland established theEndicott Board in 1885 for the purpose of modernizing the nation's coastal fortifications. Chaired bySecretary of WarWilliam Endicott, the board recommended new defenses at 22 U.S. seaports, deeming San Francisco Harbor second only to that ofNew York in strategic importance. As a result, an extensive series of forts, batteries, and guns were built on the harbor, including Fort Mason.[18]

In 1904, the previousDivision of the Pacific (1869–91) was re-established and formally stood up as thePacific Division with subordinate or related commands, including theDepartment of California (to include theHawaiian Islands) and theDepartment of the Columbia.[19] ThePacific Division was headquartered at Fort Mason,San Francisco.[20] By the end of 1907, theWar Department, underSecretary of WarWilliam Howard Taft, had eliminated the echelon of administrative units called Divisions and subsequently the Pacific Division that same year.[21] Notably, the first and only commander of the Pacific Division wasMajor GeneralArthur MacArthur Jr from 1903 to 1907.[22]
Thepiers and sheds of Lower Fort Mason were originally built from 1912 to warehouse army supplies and provide docking space and a base for ships of the Army Transport Service. By this time, the US Army began to build new posts inHawaii, thePhilippines, and various other Pacific islands. Most of themateriel for those posts was shipped through San Francisco. By 1915, the three piers together with their associated warehouse had been completed, andFort Mason Tunnel driven under Upper Fort Mason to connect with theState Belt Railroad along theEmbarcadero.
With these new facilities, Fort Mason was transformed from a harbor defense post into a logistical and transport hub for American military operations in the Pacific.[23] The Army ferryUSAT General Frank M. Coxe provided scheduled transportation from Fort Mason to the processing center at Fort McDowell on Angel Island up to eight times per day during the war.USAT Meigs was used to transport cavalry horses from Fort Mason's pier toFort Mills.

The San Francisco Port of Embarkation, a new command, was created on 6 May 1932 under Brigadier General Charles S. Lincoln with headquarters at Fort Mason assuming command over the Army Transport Service, the San Francisco General Quartermaster Depot at Fort Mason and the Overseas Replacement and Discharge Service atFort McDowell, California.[24][note 1]
With the rest of the world at war since 1939, the U.S. Army began updating and improving facilities across the country, without however an improved budget. On 1 October 1940 Army Engineer ColJohn C. H. Lee was promoted to brigadier general, and named Commanding General, Pacific Ports of Embarkation. He set up shop at Fort Mason, and spent exactly a year improving Army port facilities from Seattle to San Diego.

During World War II, Fort Mason became the headquarters of the San Francisco Port of Embarkation, controlling a network of shipping facilities that spread across the Bay Area. Thirteen installations in the San Francisco area beyond Fort Mason were part of the San Francisco POE.[3] Oceangoing ships used 20 piers with 43 berths with the port having storage space of 2,867,000 sq ft (266,353.0 m2) in warehouses, 1,984,000 sq ft (184,319.6 m2) in transit sheds and 7,640,000 sq ft (709,779.2 m2) of open space storage.[25] Other facilities included the piers at Alameda, theRichmond Parr Terminals, an Air Force depot, the Emeryville Ordnance Shops,Hamilton Field for air shipments and thePresidio which included an animal depot. TheStockton Piers and theHumboldt Bay Piers were more distant elements of the port.[3] The largest facility in the bay was what was to become the 624.5 acres (2.527 km2)Oakland Army Base at the terminus for the transcontinental railroads.[3][25]Camp Stoneman was the principal troop staging area for and under the command of the San Francisco Port of Embarkation.[26]
During the early months of the War, Lieutenant Ronald Reagan, US Cavalry Reserve, was assigned to a planning unit ("The Backroom Boys") commanded by Colonel Phillip T. Booker.
Over the years of the war, 1,647,174 passengers and 23,589,472 measured tons moved from the port into the Pacific.[note 2] This total represents two-thirds of all troops sent into the Pacific and more than one-half of all Army cargo moved through West Coast ports. The highest passenger count was logged in August 1945 when 93,986 outbound passengers were loaded.[23]
TheKorean War in the 1950s also kept the post busy, and in 1955 theSan Francisco Port of Embarkation was renamed theU.S. Army Transportation Terminal Command Pacific.
The embarkation operations continued through the early sixties. In 1965 the headquarters of the US Army Transportation Terminal Command were transferred to theOakland Army Terminal, and most of Fort Mason's embarkation facilities fell into disuse. The Army continues to use and maintain the old officer housing. TheNational Park Service took over the administration of the site in the 1970s as a part of the Golden Gate National Recreation Area. In 1976 lower Fort Mason became the Fort Mason Center, a non profit organization that provides a destination for programs, events and organizations that support and reflect the evolving cultural fabric of San Francisco and the Bay Area. (GGNRA).[27][28]


Some of the old officer housing remains in use by the Army, while some is rented to the public. One of the larger buildings has been converted into ayouth hostel, operated byHostelling International USA.[29]
As a whole, the former post is now a mix of parks and gardens and late nineteenth and early twentieth century buildings that are still in use. A path follows the harbor edge, rising along the headland and offering views north pastAlcatraz and west to theGolden Gate Bridge.
The lower portion of the site is known as the Fort Mason Center for Arts & Culture (FMCAC). FMCAC is a non-profit and their campus houses theSan Francisco Museum of Modern Art Artists Gallery,Blue Bear School of Music,City College of San Francisco Art Campus,The Interval,Greens Restaurant, Readers Bookstore,Magic Theatre, the Mexican Museum, Embark Gallery, Off the Grid,BATS Improv,San Francisco Children's Art Center,Museo ItaloAmericano,Flax art & design,California Lawyers for the Arts and other organizations connected to arts and culture.[30] The newest space is Gallery 308, whose inaugural exhibition wasJanet Cardiff'sThe Forty Part Motet (November 14, 2015 – January 18, 2016), followed bySophie Calle'sMissing (June 22, 2017 – August 20, 2017). From 2017 until its closure in 2022, theSan Francisco Art Institute opened a graduate program campus, housed in FMCAC's historic Herbst Pavilion.
The National Park Service headquarters for both the Golden Gate National Recreation Area and theSan Francisco Maritime National Historical Park are located in Fort Mason.[31][32]
Operations for theUnited States Park Police are located in the fort, providing police services for the Golden Gate National Recreation Area in San Francisco and Marin County.
A proposal exists to extend theF Market & Wharves orE Embarcadero historicstreetcar line to a terminal at Lower Fort Mason. This extension would run from the vicinity of the existing terminal nearFisherman's Wharf, westward alongside the San Francisco Maritime Museum and Aquatic Park, and then through the existing, now unused,San Francisco Belt Railroadtunnel under Upper Fort Mason.
A technical feasibility study, under the aegis of the National Park Service andSan Francisco Municipal Railway, was completed in December 2004. AnEnvironmental Impact Statement for the extension, involving the San Francisco Municipal Railway, National Park Service andFederal Transit Administration, commenced in May 2006.[33] The Draft Environmental Impact Statement (DEIS) was completed in March 2011, and was scheduled to be reviewed by December 2011.[needs update]
