John Hancock Center

The John Hancock Center at 875 N. Michigan Ave. in Chicago, Illinois, is a 100-story, 1,127-foot (344 m) tall skyscraper designed by structural engineer Fazlur Khan of Skidmore, Owings and Merrill. When completed in 1969, it was the tallest building in the world outside New York City. It is the third-tallest skyscraper in Chicago and the fifth-tallest in the United States, after the Sears Tower, the Empire State Building, the Bank of America Tower and the Aon Center. When measured to the top of its antenna masts, it stands at 1,500 feet (457 m). The building is home to offices and restaurants, as well as about 700 condominiums and contains the highest residences in the world. This skyscraper was named for John Hancock Mutual Life Insurance Company, a developer and original tenant of the building. The 95th floor has long been home to a restaurant, the latest tenant being "The Signature Room on the 95th Floor." While patrons dine, they can look out at Chicago and Lake Michigan. The Hancock Center's observation facilities (called the Hancock Observatory) compete with the Sears Tower's Skydeck across town. The Hancock Center is in a commercial district, while the Sears Tower is in the financial district. The Hancock Center 94th floor observation deck displays exhibits about the city of Chicago. Maps explain the view in each direction and a special meshed-in area allows the visitors to feel the winds 1,030 feet (314 m) above ground level. The 44th-floor sky lobby features America's highest indoor swimming pool.
