The Lake County Jail at 912 Harrison Avenue in Leadville was completed in 1901, a few years after the worst of the silver crash had already reshaped the city's economy. Leadville's population had dropped from a peak above 15,000 in the 1880s to a fraction of that by the turn of the century, but it remained the county seat of Lake County, and the jail was a practical necessity for a functioning county government.
The 1901 building represents a period of institutional construction in Leadville that followed the Victorian-era commercial boom buildings that line the lower reaches of Harrison Avenue. The jail's brick construction and utilitarian design followed the functional architecture typical of county correctional facilities of the era.
The building was later converted to the Leadville Heritage Museum, which is operated under the City of Leadville's cultural institutions. The museum focuses on Leadville's silver mining history and preserves documentary and material records of the city's 19th-century boom years. The official Leadville city website lists the Heritage Museum as one of the town's operated cultural sites.
Leadvilletwinlakes.com documents the former jail building as one of Leadville's reported haunted locations, with specific accounts of multiple apparitions associated with the building's history as a place of incarceration.
Sources
The Leadville Heritage Museum's paranormal accounts are rooted in the building's history as a working jail rather than in a single dramatic incident. Multiple former prisoners are reportedly active in the building — a diffuse haunting pattern consistent with a space that held dozens of incarcerated people over several decades of operation.
The apparition of a little girl is among the more unexpected accounts from the building. No specific historical identity has been established in available sources for this figure, and the child apparition at a county jail is an anomaly that has drawn attention in documented accounts of the location.
Two jailer figures are also reported. A former male jailer appears in witness accounts from both the jail era and the building's post-conversion years. The female jailer named Rosie — described as still conducting rounds through the building's corridors — is the most specifically named and detailed of the apparitions. The description of Rosie 'making rounds' suggests a residual-type account, where the figure is seen repeating the actions of her working life rather than interacting with visitors.
Leadvilletwinlakes.com is the primary source documenting these specific apparitions, including the named Rosie and the specifics of the prisoners and child figure.

Creede, CO
Silver was discovered in Creede, Colorado in 1889, and within a year the town had grown from nothing to 10,000 people. It drew some of the frontier era's most notorious figures: Bob Ford (who killed Jesse James in Missouri in 1882) and con man Soapy Smith both operated there. The mines closed in 1985. Local miners subsequently blasted 600 feet of tunnels into the cliff above town to create the Underground Mining Museum, which opened to preserve Creede's silver era history.
Tuscaloosa, AL
Gorgas House was built in 1829 as a dining hall for the newly founded University of Alabama. It is the oldest surviving building on the campus. Confederate Brigadier General Josiah Gorgas, who served as the Confederate Army's chief of ordnance during the Civil War, became president of the University of Alabama and lived in the house from 1878 until his death there in 1883.
Brunswick, GA
The Hofwyl-Broadfield Plantation was established in the early 1800s by William Brailsford along the Altamaha River, producing rice through the labor of enslaved people on a flood-controlled tidal system. The property passed through several generations of the Troup and Dent families. Ophelia Troup Dent, the last heir, donated it to the state of Georgia in 1973. It is now a Georgia State Parks Historic Site and is listed on the National Register of Historic Places (reference #76000635).
