The building, vacated by its dwindling congregation in 1968, was listed on the National Register of Historic Places in 1976.
It is set just south of the triangular Judge Henry Crowley Park at Saint Mark's Square.
The church is laid out in a cruciform shape, characteristic of Romanesque architectural tradition, with the nave running north-south, and the transept in an east-west orientation.
The walls are constructed of locally quarried variegated Brighton ledge stone, with trimmings of gray Nova Scotia sandstone and heavy columns of Indiana limestone.
