Idaho Territory was less than 10 years old when the territorial prison was built east of Boise in 1870. The penitentiary grew from a single cellhouse into a complex of several distinctive buildings surrounded by a high sandstone wall. Convicts quarried the stone from the nearby ridges and completed all the later construction. Over its century of operation, the penitentiary received more than 13,000 convicts, of whom 215 were women. Spurred in part by conditions that sparked a general riot in 1971 and an even more severe riot in 1973, the inmate population was moved to a modern penitentiary south of Boise and the Old Idaho Penitentiary was closed on December 3, 1973. Visitors begin with a video presentation recalling prison history, notorious inmates, and daily prison life. Once inside the Yard, they can imagine life in the foreboding sandstone cellhouses, see the contrasting beauty of the historic rose gardens, and view the effects of the 1973 riot. They may also visit Solitary Confinement, known as "Siberia," as well as Death Row and the Gallows.
