In Boise, Idaho, the Old Idaho Penitentiary haunting holds tales of confinement, unrest, and paranormal activity that draw ghost hunters and curious visitors alike. Established in 1872 and operational for over a century, the penitentiary housed some of Idaho’s most notorious criminals.

History of the Old Idaho Penitentiary
The Early Days and Notorious Inmates
Constructed from local sandstone by the prisoners themselves, the Old Idaho Penitentiary began as a simple territorial prison and expanded over the years. The prison became notorious for housing violent criminals and was the site of multiple executions and deaths, including executions by hanging.
Notable inmates include “Lady Bluebeard” (Lyda Southard), one of America’s first female serial killers, and other inmates whose ghostly presences are said to remain.

Life inside the prison was harsh, with overcrowded cells and difficult conditions leading to riots and uprisings. The prison eventually closed in 1973 due to outdated facilities and the inhumane conditions.
However, some believe that the souls of former inmates are unable or unwilling to leave the penitentiary, creating an environment ripe for paranormal encounters.

I have been interested in the paranormal for more than 15 years now. Writing about the most haunted locations around the world has been a fun experience. You just can’t beat a good EVP of foot steps or a video clip of a shadow person when it hits the web. I have been on 2 ghost hunts in my life and I hope to be doing more as I research these locations. (Hint: I dislike the REM pod)
