Springfield Penitentiary

Springfield Penitentiary is the main prison in Springfield.

Homer was held at Springfield Penitentiary after he was framed for committing financial fraud at Ziffcorp. However, he was released a day afterwards and replaced with Artie Ziff when he decided to do the right thing and turn himself in. Mr. Burns was also placed in the Springfield Penitentiary after it was discovered that he stole the Concert painting, but Homer, Lenny, and Carl busted him out in order to replace Waylon Smithers. The Springfield Penitentiary was also forced to release all minor offenders due to cutbacks as a result of a major financial crisis.
