This is a prison in Greg's city. It is first mentioned in Rodrick Rules that Anna Wrentham is said by Greg to be in prision. In Cabin Fever, the prision is shown and Greg is afraid that due to the school walls incident, he might get arrested and Greg's class also once visited a prison and had prisoners tell about their life. In Hard Luck, Greg imagines himself to be in the prison if he buys a holiday-homework from Erick Glick.
