After a large portion of land was offered to the Catholic Church by Louis-Théodore Besserer, the college moved once again, in 1856, to the current location in the Sandy Hill area. This building was constructed in stages and by 1887 it had expanded to cover the entire length of Séraphin Marion between Waller and Cumberland. The building accommodated over 400 students with classrooms, dormitories, a museum, laboratories, and an impressive chapel.
