Immanuel Congregational Church
Also known as: St. Mark's Congregational Church; Union Baptist Church
Why it's listed
Built in 1898 on Decatur Street in Bedford-Stuyvesant, Brooklyn, this two-story church was designed by architect Axel S. Hedman for the newly formed Immanuel Congregational Church. Its five-bay facade of yellow Roman brick has a rusticated first floor, round-arched stained-glass windows, terra cotta swags, a sheet metal frieze and a pediment flanked by two louvered towers. Inside, a nearly square sanctuary with galleries on three sides recalls the Congregational meetinghouse, while sliding partitions allowed classrooms to open onto the main space. Original woodwork, plasterwork, stained glass and a coffered ceiling remain. The congregation was later renamed St. Mark's, and in 1945 the building was sold to Union Baptist Church, which added a basement hall in 1961 and a baptismal addition in 1973. The church continues to serve as a house of worship and a base for neighborhood outreach, and is valued as a landmark of late nineteenth-century architecture.
Significance in brief: The nomination argues the church is an exuberant example of late nineteenth-century neo-Renaissance ecclesiastical architecture, with a sophisticated classical sanctuary and high-quality materials. Its auditorium plan with galleries and sliding partitions reflects Congregational meetinghouse tradition and the Akron-plan. It also represents the growth of Congregationalism and the development of Bedford-Stuyvesant, and later served as a key institution for Union Baptist Church.

What listing means for this property
Religious properties are listed for their architectural or historical significance, not their religious use. Listing is honorary and does not restrict the congregation's use of the building. The federal rehabilitation credit is generally unavailable unless part of the building is income-producing; some state programmes and preservation grants do cover religious buildings. Federal funding or permits trigger Section 106 review.
