Madonna Catholic High School, a girls school, and Roncalli High School, a boys school, merged in 1968 to become Aurora Central Catholic. The first campus was located on the East Side of Aurora, Illinois, USA, in what is now Cowherd Middle School. The current location of the school is on Aurora's West Side.
