Towering above the narrow streets of 17th-century Nieuw Amsterdam are some of the city’s finest 20th century skyscrapers. Included are the best of Ralph Walker, once voted the “architect of the century” by his peers: the delightfully decorative New York Telephone Company headquarters, the ponderously massive Western Union Building, and the Gothic-modern fantasy of the Irving Trust tower at No. 1 Wall Street, as well as such marvels as the Art Deco encrusted Cities Service headquarters.
