Plan on a couple hours here...pretty cool stop over that's out of the way from Downtown. While Idaho specific (obviously), this does give good perspective on what prisons were like for the time periods. © TIFA 2003

Great place to visit and experience what the prisoners had to endure to survive. So much history displayed inside. Very pretty rose gardens.

Great way to spend a few hours with the kids. Enjoyed the history and learning about the prisoners. Beautiful flowers, to boot.
