100th floor of the World Financial Center
The World Financial Center, at 1,614 feet tall, is the eighth tallest building in the world. The building contains shopping, offices, a hotel, and an observation deck.
There is a rectangular shaped opening at the top of the building that is designed to reduce the effects of wind on the building. The original plan, which called for a round opening, was rejected by the Chinese because they felt it looked too similar to the rising sun of the Japanese flag.
The new design is unofficially referred to as the \"bottle opener\" and this has been commercialized in as an item for sale in Shanghai gift shops.
