WebsiteThe "Old Pen" is a view of prison life in the West over the span of 100 years. The castle-like fortress was built in 1870 and was enlarged over the years, often with prisoner labor, until 1973 when a new prison replaced this one. Visitors take a 90-minute tour through solitary confinement cells, death row and the gallows. It is also the site of Idaho's only hanging in 1957. The building also houses several museums within the museum. Admission fees: USD5 for adults, USD4 for seniors and USD3 for kids (6-12).
