The Beinecke Library is an
International Style building. Its six-story above-ground glass-enclosed tower of
book stacks is encased by a windowless façade, supported by four monolithic
piers at the corners of the building. The exterior shell is structurally supported by a steel frame with pylons embedded to
bedrock at each corner pier, and the façade is constructed of translucent
veined marble and granite. The marble was quarried from
Danby, Vermont, and milled to a thickness of in order to allow filtered daylight to permeate the interior in a subtle golden amber glow. Gordon Bunshaft attributed the inspiration for this effect to "what I thought was
onyx in a Renaissance-type palace in
Istanbul," referring to the
alabaster used in the
Dolmabahçe Palace hammam. These panels are framed by a hexagonal grid of Vermont Woodbury granite veneer, fastened to a structural steel frame. The outside dimensions have
Platonic mathematical proportions of 1:2:3 (height: width: length). The building has been called a "jewel box", "treasure casket" (by Bunshaft himself), An elevated public exhibition mezzanine surrounds the glass stack tower, and displays among other things, one of the 48 extant copies of the
Gutenberg Bible. This level also features a secure
reading room for visiting researchers, administrative offices, and book storage areas. The level of the building two floors below ground has
movable-aisle high-density shelving for books and archives. The Beinecke is one of the larger buildings in America devoted entirely to rare books and manuscripts. File:Yale Campus from SSS roof.jpg|The Beinecke Library in architectural context, including
