Built by John D. Rockefeller, Jr. in 1921, the tiny Union Church of Pocantico Hills—an architectural beauty even then—was rendered even more remarkable by the addition in 1954 of a stained glass window by Henri Matisse (completed just before his death), and by the further addition during the 1960s of nine stained glass windows by Marc Chagall. To appreciate the artistic majesty of the windows, one must be inside the church looking out, but photography is not permitted within the structure. Still, while this rainy-day exterior shot does not do justice to the three Chagall windows depicted, it does (I hope) offer a glimpse into the beauty of the building’s Late Gothic Revival style.
