The story
La Salle began in 1858 at St. Michael's School at 2nd and Jefferson Streets in the West Kensington section of Philadelphia. Initially the Select School, it was soon renamed the Christian Brothers Academy. In 1863, it became the preparatory school to La Salle College (now La Salle University). The prep school and college shared the same campus for nearly a century, moving once in 1867 to Juniper and Filbert Streets in the heart of Center City and again in 1882 to the mansion of Michael Bouvier, a prominent Philadelphia banker, located on North Broad Street near Girard Avenue. In 1929, La Salle moved to the university’s present campus in the Logan section of upper North Philadelphia. In 1960, the preparatory school moved to the former Belcroft Estate of Clarence E. Brown. In 1982, they formally became two separate institutions, with the high school forming its own board of trustees.
