About CitySpire Center
The CitySpire Center is the tallest mixed-use skyscraper in New York City, located on the south side of West 56th Street between 6th and 7th Avenues in Midtown Manhattan. Finished in 1987, it is 248 meters (814 ft) tall and has 75 floors, with a total of 359,000 square feet (33,400 m) of area. The building is owned by Tishman Speyer Properties. Designed by Helmut Jahn, it is the ninth-tallest building in New York City and the 39th tallest in the United States. The bottom 23 floors of the tower are for commercial use and above it are luxury apartments which increase in size the higher up they are. Soon after the building's completion, residents of nearby buildings complained of hearing a loud whistling noise which, it later turned out, came from the wind blowing through the decorative dome at the building's top. The city threatened daily fines for the noise, which lasted for more than a year. Developers silenced the whistle by removing every other louver in the cooling tower, thereby widening the narrow channels through which the wind whistled.
