Autores ResumoThe Sears Tower in Chicago is the tallest office building in the world. About 1.3 million people visit the Sears Tower Skydeck each year to view the spectacular Chicago skyline. The Skydeck is located on the 103d floor, 1353 feet above the streets of Chicago. A visitor can reach the Skydeck by an express elevator that travels 1600 feet per minute or can choose to walk approximately 2100 steps. From the Skydeck, observers can see the major buildings and landmarks in downtown Chicago, including Soldier Field, Wrigley Field, Comiskey Park, the John Hancock Building, Shedd Aquarium, Adler Planetarium, and the Amoco Building. If visiting the Skydeck on a clear day, the view extends approximately fifty miles in all directions.
