A magnificent avenue of pines and moss-hung oaks leads to the entrance of the first international branch of Sacred Heart schools (founded in 1821), and the site of the only Vatican-certified miracle to occur in the United States. The miracle occurred when nuns at the convent said novenas to St. John Berchmans, a 15th-century Jesuit priest, on behalf of Mary Wilson, a very ill novice. St. John Berchmans subsequently appeared to Mary twice, and she was suddenly and unexpectedly cured. St. John Berchmans was canonized in 1888. You may enter a shrine on the exact site of the miracle and (by appointment only) tour a museum with artifacts dating from the school's occupation by Union troops during the Civil War.
