The brick Romanesque Revival-style church building, completed in 1872, now houses Faith Congregational Church, whose lineage includes the city's oldest African-American congregation, established in 1819.

The church is a stop on the Connecticut Freedom Trail and was listed on the United States National Register of Historic Places in 1993.

At the left corner between the main roof and bay a buttressed square tower rises to a steeple and spire.

The Windsor Avenue congregation was formally founded in 1869, and its first minister settled in 1871.

That congregation also built the adjacent parish house in 1904 to a design by Isaac A. Allen Jr.
