Bank of China Tower
Though it’s still a place of serious business, this iconic, I.M. Pei-designed masterpiece—impossible to miss on the Hong Kong skyline thanks to its triangle-flecked sides—allows visitors to its observation deck. When it was constructed in 1990, it was the tallest building outside of the United States—and while it’s now dwarfed by three other Hong Kong skyscrapers, it still provides sweeping views of the city. You’ll need to show your passport at the security desk.
