The Woolworth Building, 1913.
The F.W. Woolworth Company commissioned the building in 1910 to serve as their new corporate headquarters. Initially conceived as a 20-story skyscraper, designed by Cass Gilbert, it eventually significantly outstripped the original plan. On completion in 1912, the Woolworth Building stood 57-stories and cost 13.5 million dollars. In fact the neo-Gothic skyscraper was the tallest in the world between 1913 and 1930. Frank Woolworth, the building's patron, was so pleased that he gave Gilbert a 15 pound commemorative silver Tiffany bowl.
Though sold by the modern incarnation of Woolworth's in 1998, the building has been a National Historic Landmark since 1966 and a New York City Landmark since 1983.
