It was so interesting about how the prisoners were housed & how they were treated. Nothing but buckets/no toilets in some of the oldest cells with no running water. Polygamist were incarcerated due to the Latter Day saints population in the region and they were taking up a large percentage of the prison. Young boys (a 11 year old killed mother) were also jailed in a separate section. There was also a small women's building with mostly homocide females. Hanging executions were the norm. The prison was closed down in 1974 after a riot due to living conditions.

A piece of history in Boise, Idaho. Self guided walk through of different buildings in the old prison including solitary confinement and the children's ward. A must see for anyone who enjoys history and museums. Entrance is only $6.

They have an interesting and informative tour available for a fair rate. I left with a head full of history about the penal system in Idaho, particularly the former death penalty. It's also a great place to take pictures and get a little creeped out by all the old buildings and execution chamber.

Fascinating history for 6 dollars a person we were able to get a map and walk around and spend as long as we wanted I thought the women's ward was interesting but Siberia was my favorite part of the prison.
