Riverside Church, built in 1930 with the support of John D. Rockefeller, Jr. in Morningside Heights, near the banks of the Hudson River, is the tallest church in the United States. Instead of describing its height by photographing its exterior, I chose to shoot its soaring stained glass windows from the inside, and compare them in scale to the tiny figure of a caretaker walking below them. The church has long been a center of lively political discussion. Martin Luther King, Nelson Mandela, and Fidel Castro have all addressed its congregation.
