St. Peter's Episcopal Church is a picturesque Gothic Revival style building executed in wood and the congregation's second church. Built in 1849-51, the current structure replaced a smaller church built on this site in 1756-1759. Its design departed from traditional church architecture in America and was influenced instead by medieval English churches and the Gothic Revival style. Though this style was usually executed in stone or brick, the availability of lumber in this country allowed a less expensive wooden adaptation known as Carpenter Gothic. St. Peter's second and current church was designed by English-born architect Frank Wills (1822-1857), who after establishing his practice in America helped found the New York Ecclesiological Society, which promoted ancient Gothic English churches as prototypes for American parish churches of the day. Constructed as a frame, board-and-batten-clad building in the Carpenter Gothic style, St. Peter's was one of twenty-four churches Wills designed. The cornerstone was laid in September 1849, but limited funding delayed the building's use until November 1851. The church was enlarged in 1896 with the addition of the organ chamber and baptistery as two wings forming east and west transepts, and again in 1908 with the sacristy in the southeast corner and an organ loft against the north wall. In 1928, the church suffered a serious fire that destroyed much of the organ chamber and chancel area. St. Peter's was subsequently restored and survives as one of the earliest examples of the Carpenter Gothic style in New Jersey.
