The skyscraper is the most closely associated form of New York City architecture. It shifted many commercial and residential districts from low-rise to high-rise, surrounded mostly by water. The city has amassed one of the largest and most varied collection of skyscrapers in the world. New York has architecturally significant buildings in a wide range of styles spanning distinct historical and cultural periods. These include the Woolworth Building (1913), an early Gothic revival skyscraper with large-scale gothic architectural detail. The 1916 Zoning Resolution required setback in new buildings, and restricted towers to a percentage of the lot size, to allow sunlight to reach the streets below.
