The ruins of the school were dismantled in 1959 and a new Our Lady of the Angels School, located at 3814 West Iowa Street, was constructed in compliance with the latest required fire safety standards, such as installing a sprinkler system. The modern three-story building with 32 classrooms plus a kindergarten opened in September 1960. Donations from around the world helped to fund the new construction. As a result of a steady decline in enrollment during the 1990s, the Archdiocese of Chicago closed the school after the class of 1999 graduated.
