Est. 1849 · Origins in 1849, treating Gold Rush miners including scurvy-epidemic patients · Served as Tuolumne County's hospital for over a century and a half · Acute and emergency care discontinued July 1, 2007 · Acute Psychiatric Center closed December 26, 2008 · Campus repurposed for county behavioral health services rather than demolished
The roots of Tuolumne General Hospital reach back to 1849, the first full year of the California Gold Rush, when medical care in the area began in a tent. Among the early patients were miners suffering from scurvy during a deadly outbreak that struck the Gold Country camps. From that improvised beginning the county built a hospital that would serve Tuolumne County for more than a century and a half.
The facility operated as a full-service acute care county hospital into the 21st century. On July 1, 2007, the county discontinued acute care, emergency room, and ancillary services at the site. The campus retained its Acute Psychiatric Center, which provided care for acutely ill psychiatric patients until it closed on December 26, 2008.
Rather than being demolished or left to decay, the campus has been repurposed. The county's Behavioral Health Department uses a portion of the buildings, and the site has hosted other county functions over the years. In the 2020s, state behavioral-health funding, including a $9.5 million award tied to California's Proposition 1, was directed toward overhauling part of the former hospital campus into a peer respite center, with work projected to continue toward the end of the decade.
The older buildings and the institution's long medical history gave the property a reputation that drew paranormal interest, including a visit by the television series Ghost Adventures, even as the campus remained a working piece of county infrastructure rather than an abandoned ruin.
Sources
The former hospital's long span as a place of treatment, suffering, and death made it a natural magnet for ghost stories. Regional Sierra Foothills haunted-place roundups describe the now-partly-vacated hospital as believed to be haunted by the spirits of former patients, with visitors reporting apparitions and strange sounds.
The site's highest-profile paranormal moment came when the television series Ghost Adventures filmed at the hospital, the kind of attention that fixes a location in the regional haunted-tourism imagination. That exposure, combined with the building's age and its decades as both a general and a psychiatric hospital, is the basis of the lore.
Two cautions apply here. First, the haunting itself rests on a thin and largely secondary record rather than firsthand documented accounts. Second, and more importantly, the campus is not an abandoned ruin open to explorers: it is owned by Tuolumne County and partly used by its Behavioral Health Department, with state-funded renovation underway. There is no legitimate public ghost-hunting or tour access, and the appropriate way to regard the site is as a historically significant former hospital viewed from the public road, not a place to enter.
Media Appearances
View from Hospital Road of the former county hospital campus. The property is owned and partly used by Tuolumne County for behavioral health services, so this is an exterior, from-the-road glimpse only; the buildings are not open to the public and there is no ghost-tour access.

Los Angeles, CA
The Linda Vista Community Hospital opened in 1904 in Boyle Heights, Los Angeles, originally as the Santa Fe Coast Lines Hospital serving railroad employees. The Mission Revival building operated as a community hospital through the late twentieth century, sat vacant from 1991 to 2011 while serving as a frequent horror-film location, and was converted to senior affordable housing in 2012.
Fairfax, CA
Camp Bothin in Fairfax occupies the grounds of the former Arequipa Sanatorium, a tuberculosis treatment home for working-class women opened in 1911 by Dr. Philip King Brown. The property had earlier served as Henry E. Bothin's Hill Farm convalescent home for women and children. After Arequipa closed in the 1950s, the Girl Scouts took over the buildings, which they still use today.
Oceano, CA
Coffee Adam Rice built the Queen Anne Victorian house at 2531 Cienaga Street in Oceano in 1885 — the same year the family suffered multiple tragedies, including the death of a son in a riding accident and the deterioration of his wife's health. In 1905, the Temple of the People, a Theosophical intentional community based in the adjacent Halcyon settlement, purchased the property and operated it as the Halcyon Hotel and Sanatorium until 1925.
