The Seventh Regiment Armory, with its historically and architecturally significant interior spaces, was privately built for the prestigious, elite Seventh Regiment. The regimental rooms on the first floor were utilized for officers and for formal public, ceremonial, and reception purposes. The Veterans’ Room and Library, featuring a profusion of ornament and widely considered to be among the most significant and beautiful surviving interiors of the American Aesthetic movement, were designed and decorated by Associated Artists, the early business venture of Louis C. Tiffany, the first design director at his family company, Tiffany & Co.
