"The New Jersey Churchscape: Encountering Eighteenth- and Nineteenth-Century Churches" is a book and website from Frank L. Greenagel. Greenagel spent five years researching and photographing 1,100 churches in New Jersey and his book includes photos and background information on 225 of them.

There are approximately 1,400 churches, synagogues and meetinghouses in New Jersey that were built before 1900. Greenagel has been photographing and researching them for 9 years, and is in the process of publishing a complete, county by county inventory of all the surviving 18th and 19th century churches in the state. Hunterdon, Morris, Somerset, Sussex, and Warren Counties have been completed as of 2007.
