INSTITUTION INFORMATION
The State of Wisconsin purchased this facility in 1995 to be used as a Juvenile Correctional Institution for non-assaultive male youthful offenders. The main grounds and the majority of the buildings were originally constructed in the mid 1900s. The facility originally served as a Jesuit High School and later as a Lutheran Preparatory High School. Due to the decreases of juvenile offender population in the Division of Juvenile Corrections, the Legislature in the 1997 Senate Bill 113, authorized the Department of Corrections to temporally utilize this facility for the Division of Adult Institutions.
