Three buildings comprise the complex: the brownstone
Gothic Revival parish church; the parish house, formerly a school; and a convent. The church was built in 1848–52 to the design of renowned
Brooklyn architect
Patrick C. Keely. The engineer for its construction was US Army Lieutenant
William S. Rosecrans, who would rise to the rank of Major General in the
American Civil War. "On June 14, 1849, Bishop
Bernard O'Reilly consecrated the building, committing it to the patronage of the Holy Name of Mary, Our Lady of the Isle." In 1865 the school was built directly east of the church, and also was designed by Keely. In 1886 Dudley also designed the rectory that burned in 1921. A new rectory, designed by
Ambrose J. Murphy, was erected on the same site in 1924–5. In 1937 architect
John F. Hogan altered both the church and school. In 1967, after the
Second Vatican Council,
East Providence architect Milton R. Kenyon further altered the church. ==History==
