The interiors of the New York Public Library display some of the finest stonework and vaulting in the City. The ornamental plaster ceilings are of great elegance. These rooms and staircases provide a grand approach to the facilities of one of the finest libraries in the world. Three paired, pedimented entrance doors, set beneath high arched transoms of glass, are embellished by ornamental wrought-iron borders. The great interior space of the entrance lobby is over seventy feet long and forty-four feet wide. This space is all of stone, including the two grand Staircases leading to the upper floors.
