Sydney Tower is Sydney’s tallest structure and the second tallest observation tower in the Southern Hemisphere. Soaring 1,073 feet above sea level, the Sydney Tower is the city’s tallest structure, offering 360-degree views of the compact metropolis, harbor and surrounding countryside. Designed by architect Donald Crone, the building opened to the public in 1981. Standing 260 meters (850 feet) above ground level, the building’s Sydney Tower Eye features an enclosed viewing platform that fully encircles the structure. The tower has three dining facilities, including the revolving restaurant 360 Bar and Dining. The latest addition to the Tower is a “4D” cinema, which enhances the theatrical experience with special effects like wind and bubbles.
