The first example of Greek Revival architecture in Boston, St. Paul’s was a strong contrast to the colonial “meeting house” appearance of the Park Street Church (1809) across Tremont Street. The light Quincy granite, used for the body of the building, was brought from the quarries on the first railroad operated in the United States. The Ionic columns on the portico are of brown sandstone quarried from the region of Acquia Creek in Stafford County, Virginia.
