and rusticated-marble walls. John B. Smeraldi was commissioned to paint the Terrace Room's ornamentation. The room is surrounded by a balcony, with a painted coffer ceiling possibly commissioned by Smeraldi, as well as marble pilasters and floors. A balcony runs slightly above the room on its southern wall. Immediately south of the balcony is the Terrace Room's corridor and foyer. The southeastern corner of the ground floor originally contained the 58th Street Restaurant, which was exclusively for the hotel's long-term residents. In 1934, it was replaced by a nightclub called the Persian Room, which had red and Persian-blue upholstery by Joseph Urban, five wall murals by Lillian Gaertner Palmedo, and a bar. The room operated until 1978. Ballroom The original double-height ballroom from Hardenbergh's plan was on the north side of the second story, or floor 1 according to the Plaza Hotel's floor numbering system. The old ballroom, with a capacity of 500 to 600 people, was served by its own elevator and staircase, and contained a movable stage. The old ballroom was overlooked on three sides by balconies, and contained a white-and-cream color scheme similar to the current ballroom. It was served by its own entrance on 58th Street. By the 1970s, the old ballroom was replaced by offices. The current ballroom on floor 1 is at the center of that story. It was initially designed by Warren and Wetmore, and had a capacity of 800 people for dinners and 1,000 people for dances. The room contained a coved ceiling designed by Smeraldi, with crosses, hexagons, and octagons, as well as six chandeliers. The ballroom had a stage on its western wall, within a rectangular opening. A balcony ran across the three other walls and was supported by pilasters with bronze capitals. In 1929, Warren and Wetmore's ballroom was reconstructed according to a neoclassical design by Schultze & Weaver. The room has a white-and-cream color scheme with gold ornamentation, evocative of the original ballroom's design. The stage remains on the western wall, but is within a rounded opening. The redesign added audience boxes, with decorative metal railings, on the north and east walls. The ballroom contains a coved ceiling with roundels, lunettes, bas reliefs, and two chandeliers. South of the ballroom proper is a corridor running west to east. The corridor has a decorative barrel-vaulted paneled ceiling and had a balcony that was removed during the 1929 redesign. On
