In a manner contrary to Ecclesiological doctrine, which governed the design of most Episcopal churches in the second half of the nineteenth century, St. Paul's Episcopal Church is Romanesque Revival rather than Gothic. It is one of Michigan's earliest churches in that mode. In 1851, St. Paul's sold its old church built by Lemuel S. House to the Free Will Baptist Society. This new church is a major work of Otis of Buffalo, New York, who seems to have been a pioneer architect in the Midwest. It is an orangish-tan brick building on a sandstone foundation, with helmeted square towers at the corners of the west-facing facade. Round-arched windows set within corbeled panels pierce the walls. Hubbell and Langdon built the church in 1850–1852. Paine-Spiers Studios created the World War II memorial stained glass window between 1946 and 1948. Tiffany and Lamb Studios of New York City and others did the earlier stained glass windows.
