Old Montana Prison

The story

Montana’s territorial prison was built literally by the hands of the men condemned to inhabit it, operating from 1870 until its final decommission in 1979. The massive sandstone walls and the 1912 convict-built cell house held a century’s worth of territorial cutthroats, highwaymen, and state convicts inside iron cages locked within stone vaults. The pressure inside finally exploded on April 16, 1959, when inmate Lee Smart co-led a notorious prison riot, shooting Deputy Warden Ted Rothe dead and seizing control of the facility until the Montana National Guard ended the standoff with bazookas and dynamite.

Tucked into the complex is one of the American West’s most grimly pragmatic pieces of hardware: the 'Galloping Gallows.' Rather than building permanent gallows in every remote judicial district, state authorities constructed this portable timber scaffold on wheels, towing it across Montana counties whenever a local sentence called for execution. It sits quietly on the grounds now, parked permanently near the sandstone cell blocks.

While daytime visits let you walk the grounds on a standard tour, the night lock-ins are where the site turns properly eerie. From 8 p.m. to 2 a.m., after-dark investigations lock visitors inside the complex with access to restricted areas like the upper catwalk tiers of the cell house and the Death Tower—places where a century of isolation, riots, and quiet violence left their mark on the cold masonry.
