Taiwan Taichung Opera was designed by Japanese architect Ito Hiroshi. It claims to be the most difficult building in the world because of its beamless "curved wall" construction method. It took Taiwan 5 years to complete her. It has designed the world's most unique culvert wall architecture with the concept of human's most primitive "cave" and "crypt" with the surrounding water fountain. The curvilinear architecture and curvilinear reflection are interesting as if the interweaving of reality and dream. Guests travel through the buildings. the whole image as if in the dream; as if in a drama.
