Stonewall Penitentiary

Stonewall Penitentiary(Formerly known as International Prison Of Pennsylvania) is a prison in King Of Prussia, Pennsylvania. It first appeared in Mighty Carl 3, although Uncle Matty was most likely taken there at the end of the first story. The name Stonewall Penitentiary was first introduced in The Mighty Carl 5.

Stonewall's most dangerous criminals are Matt and Calvin Cable who have a high escape/criminal record. Stonewall in general has a poor security record, and high escape rate. Sid The Science Kid may have been locked up there at the end of The Four Rejects story.

Fun Fact: If villains in the Miles Universe end up being taken to jail, then they are usually incarcerated here.
