The present church building, an architecturally distinctive blend of Romanesque and Georgian Revival styling, was built in 1870 for a congregation established in 1820.

[1] The church stands on the south side of Main Street (United States Route 20), one block west of Waltham's Central Square.

Its main body is oriented north-south, with a gable roof, and a square tower rising at the northeast corner.

The building was built in 1870, and originally had Italianate styling, some of which is still evident in its round-arch windows and bracketed gable.

Growth in the congregation prompted construction of this larger structure in 1870 to a design by Boston-based Thomas Silloway.
