Est. 1836 · First State Prison West of Mississippi · 40 Executions by Gas Chamber · 1954 Prison Riot
Wilson Eidson arrived at the Missouri State Penitentiary on the banks of the Missouri River in Jefferson City in 1836, sentenced for stealing a watch. He was the first inmate in what would become the oldest continuously operating prison west of the Mississippi, a facility that would house hundreds of thousands of people over the following 168 years.
The penitentiary grew incrementally across the 19th and early 20th centuries, adding cell blocks, administrative buildings, and industrial facilities as the Missouri prison population expanded. At its height the facility held approximately 5,000 inmates across its 47 acres, making it one of the largest prisons in the United States by population. The cell blocks that remain standing include some of the original 19th-century construction alongside 20th-century expansions.
The gas chamber, installed in the mid-20th century, was used to execute 40 men and women — a number that puts the Missouri State Penitentiary among the more active execution facilities in American history. The chamber itself survives intact and is accessible on tours.
The 1954 riot is the most documented violent incident in the prison's history. On September 22 of that year, two inmates faked illness to draw guards to their cells, took the guards' keys in an ambush, and within hours had released inmates across multiple cell blocks. When the uprising ended, four inmates were dead, 29 were injured, and one had attempted suicide. The phrase attributed to Guy Magazine — 'the bloodiest 47 acres in America' — circulates in connection with this incident and the prison's broader history of institutional violence.
The prison closed in 2004 following a federal consent decree. The State of Missouri retained ownership. The Jefferson City Convention and Visitors Bureau now operates the facility as a museum and event venue, offering history tours, ghost tours, and paranormal investigation experiences year-round with a winter closure.
Sources
The paranormal investigation record at Missouri State Penitentiary benefits from the facility's own documentation program. The penitentiary employs a Paranormal Program Manager and maintains a structured schedule of public and private investigation events, which means the accumulated witness record is larger and more systematically collected than at most investigation venues.
The coin sound in Housing Unit 4 has become the property's signature account. Multiple tour guides, working different shifts on different dates, have reported the same experience: a distinct metallic clink, the sound of coins falling against the concrete floor, in a section of the unit where no one is standing and where no coins or loose objects are present. The guides' descriptions, collected independently, describe the same sound in the same location.
Ghost Adventures filmed at the Missouri State Penitentiary and documented activity in the original cell blocks and the area near the gas chamber. Paranormal Lockdown also produced an episode at the facility. The investigative footage from both productions shows equipment responses — EMF spikes, temperature drops, audio anomalies — concentrated in the oldest sections of the building.
Tour guides have reported being poked from behind when walking in Solitary Confinement, turning to find no one there. The entity associated with this account is described as a guard who died in Solitary Confinement in 1932 and is said to continue his rounds. Cold spots in the cell blocks and apparitions near the gas chamber are among the most frequently reported phenomena.

Petros, TN
Brushy Mountain State Penitentiary opened in 1896 in the aftermath of Tennessee's Coal Creek War, built in part by the convicts who would subsequently mine coal on the same grounds. The prison operated for 113 years before closing in 2009, housing notable inmates including James Earl Ray — the convicted assassin of Martin Luther King Jr. — who made a 1977 escape using a pipe ladder and was recaptured after 54 hours.
Ione, CA
The Preston School of Industry in Ione, California was established by the State Legislature as a reform institution for juvenile offenders — emphasizing rehabilitation over imprisonment. The cornerstone was laid in December 1890, and the Romanesque Revival building, designed in the Richardsonian style, opened in June 1894. The school operated until 1960, when new facilities were completed on the same property. Notable alumni include Merle Haggard, Rory Calhoun, and author Eddie Bunker.
Mansfield, OH
The Ohio State Reformatory in Mansfield was built between 1886 and 1910 on 40 acres, designed by architect Levi T. Scofield in a blend of Victorian Gothic, Richardsonian Romanesque, and Queen Anne styles intended to encourage spiritual reform in young offenders. The facility opened September 15, 1896, and operated until 1990 when a federal court ordered its closure due to overcrowding and inhumane conditions. Over 200 people died during its operation. The Mansfield Reformatory Preservation Society has operated it as a museum since 1995.
