The Conventual Church of St. Mary and St. John is a historic Episcopal church in Cambridge, Massachusetts. The Romanesque Revival church was built in 1936 to a design by architect Ralph Adams Cram. Cram sought to reproduce 12th century ecclesiastical forms found in the Burgundy region of France. The building was featured in a 1941 architectural magazine.[1] It is home to monks of the Society of Saint John the Evangelist of the Episcopal Church.
The church was listed on the National Register of Historic Places in 1982.
