St. George's School and Convent

St George's School and Convent are a historic Roman Catholic complex at 124 Orange Street in Manchester, New Hampshire, United States. The school and convent are a pair of connected three-story brick buildings, constructed in 1898-99, along with a church (which is across the street, and now non-denominational Protestant) to serve the large French Canadian community that had migrated south from Quebec to work at the Amoskeag Mills, the city's largest employer. The complex is the only surviving Catholic facility of the period on the east side of the Merrimack River, and is one of its best examples of Romanesque architecture. The two buildings are connected by a brick connector constructed in 1915 when the convent was converted for academic use. The school closed in 1970, after which time the buildings have been used to house social service agencies and act as a community center.

The buildings were listed on the National Register of Historic Places in 1985.
