The Ping An Financial Center has recently completed construction and opened to the public, making it the fourth-tallest building in the world officially. Located in the Futian business district in Shenzhen, China, the building rises a neck-aching 599 meters, with 100 floors that hold offices for Ping An's 15,500 employees.
Though it's technically an office building, the Ping An Financial Center's sheer size makes it an attraction for tourists as well. The building has an observation deck at the very apex, which the architects expect to draw as many as 9,000 visitors daily (which adds up to 3.2 million visitors annually.)
Not only is the building architecturally interesting thanks to its tapered form and elegant chevrons, but it's also something of an engineering marvel. Though Shenzhen is wet and stormy, which would make any super-tall building a lightning risk, the Ping An Financial Center uses stainless steel piers that deter electricity.
