The ionic Oriental Pearl Tower. At 1,535 feet high, it is the tallest completed tower in Asia. The tower features 11 spheres, big and small. The two biggest spheres, along the length of the tower, have diameters of 164 ft for the lower and 148 ft for the upper. They are linked by three columns, each 30 ft in diameter. Regrettably this was the best photo I could manage.
