1. Cunard Building

The Italian neo-Renaissance lobby of the Cunard Building, an interior landmark recently re-opened as an event venue by Cipriani, was designed by architect Benjamin Wistar Morris. This masterpiece features 65-ft high ceilings, soaring marble columns, and magnificent inlaid floors. The grandly presented marine theme of the decor underscores the power and reach of the Cunard Line, as the building opened at a time when New York had recently become the largest city and busiest port in the world. Previously only accessible for special events and film shoots (as seen in The Blacklist), this weekend will be a first in terms of public entry.
