7. Bank of China Tower, Hong Kong

Height: 305 meters

Cost to build: NA

Completion date: May 1990

Fast fact: The building was criticized by feng shui masters for its sharp corners, which in feng shui terms means it will bring bad luck to its neighbors (notably the HSBC main building). Pei had to modify the design before construction began.

The Bank of China Tower was the first skyscraper outside of the United States to surpass the 305-meter mark and was once the tallest building in Hong Kong.

Reflecting lights like a glittering crystal, the unusual crystalline-like structure is inspired by the bamboo plant, mimicking its strength, vitality and growth.

It has for years been one of the most distinctive buildings in Hong Kong, out-shining its taller neighbors.

Together with Two IFC, the tower is part of the city's Symphony of Light show, illuminating Hong Kong's harbor every night at 8 p.m.
