Old Idaho Penitentiary

The Old Idaho Penitentiary was operational from 1870-1973 and is one of only four Territorial Prisons still open. If today's inmates think they have it rough, they should consider serving time here in late 1800s when you were housed in a two man cell about the size of a walk-in closet and with only a bucket as your indoor plumbing.

There is also a surprisingly good weapons exhibit.
