Idaho State Penitentiary

The Old Idaho State Penitentiary in Boise, Idaho, was constructed in 1870 while Idaho was still a territory, making it one of the earliest correctional facilities in the region. The first structure was a single-cell house built using sandstone quarried from nearby hills, much of it cut and placed by the inmates themselves. Over time, the prison expanded into a large complex surrounded by towering stone walls, creating a self-contained facility designed to house some of the most dangerous criminals in the area.

As Idaho grew from a frontier territory into a developed state, the penitentiary grew alongside it. Additional buildings were added, including cell blocks, a hospital, a dining hall, and work areas, turning the prison into a small functioning community. The prison eventually held well over thirteen thousand inmates over its lifetime, including both men and women.

Life inside the prison was harsh and often brutal. Early inmates endured extreme temperatures due to the thick sandstone walls, which trapped heat in the summer and cold in the winter. Basic plumbing and ventilation were not introduced until decades later, and overcrowding and poor sanitation contributed to illness and suffering among prisoners.

Violence and unrest were common throughout the penitentiary history. Several riots broke out, including major uprisings in the mid-twentieth century and again in 1971 and 1973. These events caused significant damage to the facility and highlighted the growing concerns about inmate conditions and outdated infrastructure.

The prison officially closed in 1973 after more than a century of operation, with inmates transferred to a newer correctional facility. Today, the site is preserved as a historic landmark and museum, allowing visitors to walk through the original structures and experience a glimpse into Idaho's early penal system.
