above the crossing. Cram's designs were not fully built, either. The Cathedral of St. John the Divine remains only two-thirds complete and is often nicknamed St. John the Unfinished. Narthex and western facade Narthex The narthex, in the westernmost portion of the cathedral facing Amsterdam Avenue, was designed by Cram. His original plans did not include a narthex, instead showing the nave continuing as far as the western facade. Inside the narthex is a large vestibule, which serves as an entrance to the nave on the east. The vestibule measures along the north–south axis and along the west–east axis. The southern part of the narthex contains the cathedral's gift shop. Above the narthex are two towers: one named for Saint Peter to the north and the other named for Saint Paul to the south. The north tower reaches to the roof of the nave, which is above ground level; the south tower is about taller, with the additional height having been built between 1982 and 1992. If the towers had been completed, they would have been about tall. The towers protrude slightly from the northern and southern elevations of the facade but are flush with the western elevation. On the northern and southern facades of the narthex, at the base of the towers, are stained glass windows, one on each side. Western facade The narthex abuts the unfinished western elevation of the facade facing Amsterdam Avenue; this facade is wide and consists of five architectural bays. The bays are separated by large arched buttresses with finials at their tops, and they contain niches for the possible future installation of statues. The western elevation is divided into four vertical tiers. From bottom to top, they are the ground-level portals, on the first tier; the gallery level, on the second tier; the large rose window and several smaller grisaille and lancet windows, on the third tier; and the top of the south tower and the gable above the center bay, on the fourth tier. At ground level, there are five portals under arched openings. The largest of those is the center portal, called the Portal of Paradise, which contains carvings of the transfiguration of Jesus as well as St. John and 32 biblical characters; these were carved in 1988 under Simon Verity's leadership. St. John is depicted on the trumeau, or vertical pier, between the two pairs of doors within the center
