It seems wherever you are in downtown Sydney, you can look up and see the Sydney Tower Eye watching over you. This city’s tallest structure tops out at 1,014 feet. That is more than two hundred feet above the highest skyscraper. At 879 feet is an amazing observation deck. There are also three elevated restaurants. They all offer exciting, 360° vistas, making this a popular tourist attraction. Want a bigger adrenaline rush? Try the glass platform called Skywalk. Sydney Tower is located above the Westfield Sydney shopping mall. It was designed by Donald Crone and opened in 1981.
