Est. 1911 · National Register of Historic Places · Historic County Jail · Gallatin County Legal History
The Gallatin County Jail opened in 1911 next to the county courthouse on West Main Street in Bozeman. It was designed and built by Fred Fielding Willson, a prominent local architect, and is listed on the National Register of Historic Places. The Gallatin County Historical Society now operates it as the Gallatin History Museum.
The jail held prisoners for most of the 20th century, and the museum retains its original cell block. Displayed in the entry is the scaffold and metal trap door used in the 1924 execution of Seth Orrin Danner — the last legal hanging in Gallatin County and the only one carried out inside this jail.
Danner was convicted in the death of Florence Sprouse, who with her husband John Sprouse was killed in 1920. He was hanged on July 18, 1924, before roughly two dozen witnesses, accompanied by two priests and the county sheriff. The case has drawn lasting doubt: Danner's wife, Iva, later said in a deathbed account that he should not have been hanged for the crime, and a published history examines the unresolved questions around his guilt.
The museum interprets this and the broader history of crime and justice in early Gallatin County, alongside ranching, settlement, and regional exhibits.
Sources
Because the museum keeps the actual gallows and cell block, its ghost stories center on Seth Danner, hanged here in 1924. Local accounts describe cold spots and a sense of being watched near the gallows display and the old cells, and museum staff and visitors have passed along the building's reputation for years in Bozeman-area Halloween features.
A recurring piece of jailhouse lore is the 'seventh prisoner' story: in tellings of an attempted escape, inmates are said to have left Danner behind, unwilling to take him with them. The detail is folklore attached to the building's grim centerpiece rather than a documented event.
The museum has leaned into the atmosphere with a seasonal 'Haunted Jailhouse' program in some years, opening the cells after dark. Outside that event, the building presents Danner's case as history — a contested conviction and the county's only legal hanging — and the paranormal reports remain anecdotal, tied to the unusually intact setting rather than to verified phenomena.
Notable Entities
Tour the 1911 Gallatin County Jail, now a regional history museum that keeps its original cell block and a hanging gallows on display in the entry. Exhibits cover Gallatin County law-and-order history, including the 1924 execution of Seth Danner, the only legal hanging carried out in the jail.
The museum has run a seasonal 'Haunted Jailhouse' program around Halloween in some years, opening the old cells after dark. Check the website for whether the event is scheduled this season and how to get tickets.

Yuma, AZ
Yuma Territorial Prison operated from 1876 to 1909 on a bluff overlooking the Colorado River in Yuma, Arizona. It held 3,069 prisoners during its 33-year operation, including 29 women. The facility became a state historic park and has been voted by USA Today readers as the Best Haunted Destination in the nation.
St. Augustine, FL
The Old St. Johns County Jail at 167 San Marco Avenue in St. Augustine, Florida was commissioned by railroad magnate Henry Flagler and constructed in 1891. Designed by the same architectural firm later used for Alcatraz, the facility housed prisoners under conditions so severe — one bucket per cell as a toilet, minimal diet, and labor in Flagler's fields — that it was closed in 1953. Eight documented executions occurred on site before the county converted the building to a tourist attraction in 1954.
Denver, CO
The Molly Brown House in Denver was the home of philanthropist and Titanic survivor Margaret Brown from 1894 until her death in 1932. Designed by architect William A. Lang in 1889 in a mixed Queen Anne and Richardsonian Romanesque style, the house has operated as a museum under Historic Denver Inc. since 1971 after a public campaign saved it from demolition.
