Spending by visitors generates sales in lodging, food services, recreation, gas stations, and retail businesses. These sales support jobs for Missouri residents and contribute tax revenue to local and state governments.

Net profit from ticket and merchandise sales goes back into the preservation of MSP and tour enhancement. Collected since 2015, over $858.6k has gone to these efforts.

The Missouri State Penitentiary opened its doors in 1836 and at its peak was the largest operating prison in the United States. The prison is notably famous for housing inmates such as professional boxer Sonny Liston and notorious outlaw Pretty Boy Floyd. The prison was decommissioned in 2004 and opened for tours in 2009.
