Church of the Most Holy Trinity (St. Patrick's Church) is significant as one of the first examples in Georgia of the Round-Arch or Romanesque Revival style that had its origins in Germany. A number of central European architects transmitted the style to America. John Rudolph Niernsee designed the church. He immigrated to the United States to become one of the most significant architects practicing in Baltimore during the mid-19th century. The painting, sculpture, and stained glass in the church are important examples of mid-19th century fine art and decorative arts. - NPS
