Catholic Chapel The Catholic Chapel is located below the Protestant Chapel, and seats approximately 500 people. The nave is wide, long and high. The focal point of the Catholic Chapel is the reredos, an abstract glass mosaic mural designed by Lumen Martin Winter and composed of varying shades of blue, turquoise, rose and gray tessera to form a portrayal of the firmament. Superimposed on the mural and depicting the Annunciation are two tall marble figures, the Virgin Mary on the left, and the Archangel Gabriel on the right. Above and between these two figures is a marble dove. In front of the reredos is the altar, a gift from Cardinal Francis Spellman, who dedicated the Catholic Chapel on September 22, 1963. The altar is Italian white marble mounted on a marble cone-shaped pedestal above which is a six-foot sculptured nickel-silver crucifix. Along the side walls of the chapel are the 14 Stations of the Cross, also designed by Lumen Martin Winter, and carved from four-inch (102 mm) thick slabs of marble. The figures are done in Carrara marble, from the same quarries where Michelangelo drew his stone. The classical pipe organ, in the 100-seat choir loft, was designed by Walter Holtkamp and built by M.
