Saginaw architect William T. Cooper designed Clare Congregational Church in a Greek cross plan. Built in 1909, it is one of only a few churches in Michigan that reflect how early twentieth-century Protestants adopted the architecture of fifth- and sixth-century Early Christian central plan churches. Its semi-circular, auditorium-like sanctuary is embellished with patterns from European-designed stencils, and its stained-glass windows decorated the original 1874 church.
