Riverside Church, date unknown.

The church building is the tallest church building in the United States and was designed by the firm of Allen, Pelton and Collens. The architects were commissioned by the church's funder John D. Rockefeller Jr. to travel in Europe for design inspiration and it is said that the large single bell tower (392 feet tall) is inspired by the towers of a cathedral in Laon, France. The tower and its basement floors not only housed the church's bells, but also provided space for offices, social rooms, classrooms, a bowling alley, and a theatre.
