The Woolworth Building, at 233 Broadway, Manhattan, New York City, designed by architect Cass Gilbert and between 1910 and 1912, is an early US skyscraper. The original site for the building was purchased by F. W. Woolworth and his real estate agent Edward J. Hogan by April 15, 1910, from the Trenor Luther Park Estate and other owners for $1.65 million. By January 18, 1911, Woolworth and Hogan had acquired the final site for the project, totaling $4.5 million. More than a century after the start of its construction, it remains, at 241.4 meters (792 ft), one of the 100 tallest buildings in the United States as well as one of the 30 tallest buildings in New York City. It has been a National Historic Landmark since 1966, and a New York City landmark since 1983.
