Built of local fieldstone and granite quarried in Somerville, Massachusetts, the building is a notable example of the muscular use of stone, typical of American Gothic Revival architecture. This solidity, coupled with Esty's display of structural strength in the asymmetrical massing of forms, is further accentuated by the contrast between heavy gray stone and large, graceful, delicate stained glass windows, which the stone walls simultaneously reveal and protect.
In 1897, the original parish hall was lost in a fire. The rebuild was under the direction of noted Boston Theater Architect, Clarence Blackall. The most notable feature of the reconstruction is an 1890 Tiffany & Company Window. This early Tiffany window bridges the gothic stained glass tradition and emerging art nouveau movement.[2]
The church is currently home to various organizations and ministries, such as the Homeless Empowerment Project which publishes the Spare Change News street newspaper, the José Mateo Ballet Theatre, the Adbar Ethiopian Women's Alliance, the Cambridge Child and Family Associates, and others.[3]
