Zifeng Tower

Height: 1,476 feet (450 meters)

Location: Nanjing, China

Architect: Skidmore, Owings and Merrill (SOM)

The Zifeng Tower includes a 6-star Intercontinental Hotel, restaurants, extensive office space, an observatory, and a shopping center. The building's shape was inspired by Nanjing's triangular form, while the observation tower provides an all around view of the surrounding city. Unfortunately, an impressive view from this tall building may not be available thanks to China's infamous smog.
