You've probably seen the prison in St. Cloud hundreds of times on the outside. Have you ever wondered how it looks inside? We've gathered a few great videos to give you the full history and tour.

St. Cloud's State Prison is a massive complex, seen easily along hwy 10 on the Southeast side of St. Cloud. It was first opened in 1889 and the walls were built by prisoners using the granite from the prison quarry, one brick at a time. The prison is generally the initial prison felons experience before being transferred to another prison.

It holds the record for the longest granite wall in the world, and is 1.5 miles in total length.
