Saint Charles Preparatory School is a four-year Catholic college preparatory school (a type of high school) in Columbus, Ohio, US. It was founded in 1923 by the fourth bishop of Columbus, James J. Hartley, as a Roman Catholic college seminary and high school. Today, it is an all-male high school serving the Roman Catholic Diocese of Columbus. The school's patron is Saint Charles Borromeo, and its motto, inscribed above the front door, is Euntes Ergo Docete Omnes Gentes, a quote from the Gospel of Matthew (28:19) in the Latin Vulgate: "Going out, therefore, teach all nations." The original nickname of Saint Charles students is "Carolians", derived from the Latin word "Carolus," which means "Charles." In 1947, the students also began to refer to themselves as "Cardinals." The Saint Charles sports mascot is Charlie the Cardinal. Campuses and founding The school consists of two campuses. The oldest campus is Main Campus, which contains the school, gymnasium, natatorium, and theater. The newest campus is West Campus, which contains the athletic facility, track, and the robotics and mentoring center. The school was founded in 1923 by Bishop James J. Hartley. The first classes were held at Sacred Heart School, an all-girls Catholic school, while the main school building was being built. Main Campus In 1925, construction of the main school building was completed and classes were held there. In 1931, the gymnasium and the Our Lady Lourdes Grotto were completed. Major renovations were made to the gym in 1951 to more than double the capacity. A Gaelic-style chapel (called the "Lower Chapel") was added on to the east side of the school in 1937. Bishop Hartley dedicated the chapel to Mother of Mercy. A Milwaukee art company beautified the chapel with artwork in 1952. A natatorium was built next to the multipurpose room in 1990. In 1999, the Jack Ryan Training and Fitness Facility was built adjoining to the gym. Construction on the US$5.5 million Robert C. Walter Student Commons and the Student Services and Fine Arts Center, the largest addition to Saint Charles in its history, began in June 2005. The approximately addition, which replaced the courtyard behind the school, was ready for graduation at the end of the following school year; however, it was not available for full use until the 2006–2007 school year. The addition houses the Robert C. Walter Student Commons Area, which serves as a new cafeteria and
