The main building is a
Gothic Revival structure, designed by Boston architects
O'Connell & Shaw and completed in 1928. It is an elegant example of French Gothic architecture, notable for the large rose window in the front-facing gable end. The rectory is a c. 1860 Italianate villa, originally built for a member of the locally prominent Wardwell family. He has incorrectly also been given credit for the design of the church. The complex was added to the
National Register of Historic Places in 1987. ==St. Mary's Convent==
