Xavier Hall was built between 1910-11 on the campus of St. John’s Prep School in Danvers, Massachusetts. The building was constructed by the Xaverian Brothers as classrooms as the first purpose-built structure in what would become a large campus. The Neo-Gothic Revival style building was sited adjacent to Porphyry Hall, an 1880 estate house that the new school purchased in 1891, which was later expanded by the addition of a rear chapel. Edward T. P. Graham, an architect best known for his design of Roman Catholic churches and associated buildings, was hired to design the stately structure built of brick and limestone.
