The History of the Old Idaho Penitentiary

The story of the Old Idaho Penitentiary begins in 1861, during a time when the territory was still young and its laws were still evolving. The need for a secure prison to house growing numbers of convicts prompted the construction of the penitentiary on a steep hillside overlooking the city of Boise. Built with rugged sandstone blocks and a design that prioritized security over comfort, the prison’s early years were marked by harsh conditions and the struggle to maintain order amidst a growing population of inmates.

Early Days (1861-1909):

The prison’s early design was basic, with a single cell block housing male and female inmates together. Conditions were unforgiving, with overcrowding, limited sanitation, and a constant threat of violence.

Expansion and Evolution (1909-1973):

The early 20th century saw a significant expansion of the prison, with new cell blocks, workshops, and a solitary confinement unit being constructed. The introduction of more stringent security measures, like guard towers and stricter inmate rules, aimed to reduce escapes and control violence.

Closure and Legacy (1973-Present):

By the 1970s, the prison was deemed outdated and overcrowded, leading to its closure in 1973. The penitentiary was designated as a historical landmark and opened to the public in 1989, allowing visitors to explore its dark history and glimpse into the harsh reality of life behind bars.

Notable Inmates:

Throughout its history, the Old Idaho Penitentiary housed a diverse population of inmates, from petty thieves to notorious criminals. One of the most infamous was Robert Stroud, known as the “Birdman of Alcatraz,” who served a portion of his sentence at the Idaho Penitentiary before being transferred to Alcatraz.

The prison’s design reflected the prevailing attitudes toward punishment and rehabilitation during its era, with security being the paramount concern.

Notable Structures:

Some of the most notable structures within the prison include:

  • The Execution Chamber: The site of numerous executions, the chamber still retains its chilling atmosphere, with its heavy wooden door and the gallows that once held condemned inmates.

  • The Warden’s Residence: Located near the prison’s entrance, the warden’s residence served as a symbol of authority and a reminder of the power that resided within the prison walls.

Construction Materials and Techniques:
