3. 67th Street Library, Manhattan
The 328 East 67th Street library was built in 1905 also by the architectural firm Babb, Cook & Willard. You will immediately notice the unusual Art Nouveau transom window above the doorway. It has been renovated twice, restoring the original staircase, decorative iron railing and mosaic floor. Not landmarked, the 14,000 square foot interior space was also reconfigured to meet today’s needs.
