Hancock Observatory

The John Hancock building is Chicago's third highest skyscraper with a distinctive x-bracing exterior skin, and its Observatory competes with the facilities of the Sear's Tower Skydeck across town in the Financial District. Located on the 94th floor 1,000 feet (305m) above street level, the Observatory boasts the city's only open-air skywalk, as well as 360-degree views, a talking telescope, audio Skytours that provide an overview of the city with 16 stops, and the History Wall, with more than 100 photos featuring Chicago's history. Visitors can also have fun with some unique 'daring' photo opportunities. An annual 'Hustle up the Hancock' stair climb race up the 94 floors is held every February; the record time is nine minutes 39 seconds.
