Taipei 101
The 91st floor is an outdoor Observatory. The outdoor observatory is accessible by stairs from the 89th floor. From the outside, it's possible to view the spire at the 508-meter-high apex, but tourists need to be careful of the strong winds.  Inside the building, on the 91F, is a small theater showcasing films about the building and the annual New Year fireworks display. The 91st floor is only open on days with good weather conditions.
