Looking like a stucture straight out of The Jetsons, the Oriental Pearl Tower was built when much of Pudong was still farmland. It's especially kitschy at night when it flashes with colored lights. A museum in the base recalls Shanghai's pre-1949 history. Each with its own observation deck, the three spheres are supposed to represent pearls (as in the city's nickname, the "Pearl of the Orient"). Go to the top sphere for a 360-degree bird's-eye view of the city, or grab a drink in the tower's revolving restaurant (skip the food).
