It has five contributing buildings dating from 1858 to the 1920s, including a church, rectory, high school and religious education center.","why_significant":"It is Waltham's oldest Roman Catholic parish and has strong ties to the city's 19th and 20th century ethnic population. It is also a well-preserved, fully developed complex of multi-purpose buildings. The 1858 Romanesque Revival church and the 1882-83 Second Empire rectory are particularly fine examples of their styles.","narrative":"St. Mary's Church Complex occupies a 4.8-acre site in central Waltham and serves the city's oldest Roman Catholic parish. Its core is the red brick Romanesque Revival church, begun in 1858 and enlarged in 1875-77 to double its capacity, with a buttressed bell tower and octagonal spire. Beside it stands the brick rectory of 1882-83, described as one of Waltham's finest Second Empire buildings, with its original slate roof and a carriage house. A Classical Revival high school dated 1922 and a 1920s Georgian Revival religious education center complete the main group. The parish grew from a Catholic community formed in 1830, made up largely of Irish immigrants, and it later sponsored schools and helped establish other parishes for French-speaking and Italian Catholics. The complex was listed for its architectural quality, its integrity, and its role in the city's ethnic and religious history. The parish celebrated its 150th anniversary in 1985.","period_of_significance":"1858-1920s","architect_builder":"Murphy of Providence (architect of the 1875-77 church enlargement); improvements by Cowen & Hanrahan","architectural_style":"Romanesque Revival (church), Second Empire (rectory), Classical Revival (high school), Georgian Revival (religious education center)","criteria":["A","C"],"status_note":"Present use is church; general condition is described as excellent.
