The former St. Raphael's School building, which stands next to the cathedral on the south, was built in 1904 in the Neoclassical style. It replaced the boys' school and the girls' school buildings that were located in the rear of the cathedral property. The boys had been taught by a community of religious brothers. The boys' school building was located behind the girls' school and the cathedral itself and has subsequently been torn down. St. Raphael's School closed in 1976 because of low enrollment. The building was sold by the parish in the mid-1980s.
