Est. 1899 · Letterman Army Hospital (1899–1994) · Spanish-American War through Vietnam War Medical Facility · Presidio of San Francisco · Lucasfilm Digital Arts Center (2005)
Letterman General Hospital opened at the Presidio of San Francisco in 1899, taking its name from Jonathan Letterman, the Army medical director who reorganized the Union Army's medical corps during the Civil War. The hospital's timing was deliberate — the Spanish-American War was generating casualties and the West Coast needed a proper military medical facility.
Over the following century, Letterman treated soldiers returning from the Philippines, from the Western Front in World War I, from the Pacific Theater in World War II, from Korea, and from Vietnam. The hospital expanded repeatedly to meet demand; by the Vietnam era it was a major facility handling amputations, burns, psychiatric cases, and wounds of all kinds from men shipped home across the Pacific.
The Army transferred the Presidio to the National Park Service in 1994 as part of post-Cold War base closures; Letterman was vacated that year. In 2002, after years of negotiations over the site's future use, the buildings were demolished. Lucasfilm secured a long-term lease on the land and constructed the Letterman Digital Arts Center, which opened in 2005. The construction reportedly reused approximately 50% of the demolished hospital's concrete — a detail noted by SF Ghost Hunt and other sources that document the haunting reputation.
The campus is now one of the more unusual corners of the Presidio: a working private office campus within a national park, where the Yoda Fountain at the entrance draws hundreds of Star Wars fans on weekends.

The documented basis for the Letterman haunting predates its ghost-tour reputation by more than a decade. According to SF Ghost Hunt, a 1992 Army inspection — conducted while the hospital was still operational — produced reports from staff describing the sound of shuffling patient footsteps in empty sections of the building, voices heard from behind closed doors in vacant rooms, and dark figures visible in the corridors.
These reports came from military personnel working a medical facility, not from informal visitors. The context is significant: Army staff in a functioning hospital have professional reasons to avoid reporting anomalous experiences unless those experiences are persistent and specific.
Ghost hunters who gained access to the buildings during the demolition transition between 1994 and 2002 documented their own findings from the site. The SF Ghost Hunt documentation references these investigations as producing accounts consistent with the earlier staff reports.
After Lucasfilm completed the Letterman Digital Arts Center in 2005, the haunting claim evolved: the reuse of hospital concrete in the new construction became the narrative thread connecting the old hospital to the new campus. Accounts of anomalous experiences in the new buildings appear in dark-tourism sources, though they are less specific and well-documented than the 1992 inspection-era material.
The public can access the campus grounds; the building interiors are off-limits. The site's dark history is not memorialized on-site.
The Letterman Digital Arts Center grounds are open to the public. The Yoda Fountain at the campus entrance is a well-known photo stop. The public can walk the perimeter and grounds while the office buildings remain restricted. The former Letterman Army Hospital occupied this exact footprint from 1899 until demolition in 2002.

The South Pacific Coast Railroad established a depot on Station Island in San Francisco Bay in 1876, and the settlement that grew around it—Drawbridge—reached 90 buildings by the 1920s, sustained by duck hunting, fishing, and Prohibition-era speakeasies and brothels. Vandalism triggered by an erroneous Mercury News story declaring it abandoned accelerated its depopulation, and the last resident left in 1979. It is now the only ghost town located inside a National Wildlife Refuge.

The 16th Street Station opened in 1912 as the Transcontinental Railway's western terminus, designed by Jarvis Hunt in the Beaux-Arts style. It served as the West Coast headquarters of the Brotherhood of Sleeping Car Porters, the first Black-led union in the United States. The 1989 Loma Prieta earthquake severely damaged the structure and it closed in 1994, sitting vacant for decades before a restoration effort began.

The Argonaut Mine, in operation from the 1850s until 1942, was the site of the deadliest gold-mining disaster in California history. On August 27, 1922, a fire broke out at a depth of approximately 4,650 feet and killed all 47 trapped miners — most of them Italian, Spanish, and Serbian immigrants — before rescuers could reach them.
