National Taichung Theater is located in Xitun District, Taochung. It is a very characteristic performance area. The theater is designed by Japanese architect Toyo Ito. Using the concept of the primitive caves and holes, Toyo Ito designed the world first and only Sound Cave Curved Wall for National Taichung Theater. There are no vertical and horizontal structures and it’s the world’s first curve surfaced hanging structure architect. Due to the complexity, it is known as the most difficult architect to complete. Five years and NT$ 4.36 billion, the theater finally open in November 23rd, 2014. The theater is organized into a large theater, medium theater and experimental stage, which hold up to more than 3000 guests.

During the urban renewal in Taichung, Taichung city government tried get the Guggenheim Museum to join the museum project in Taichung. Unfortunately due to the budget shortage, the project was canceled. After Architecture Design Competition for the later idea to build a national theater, Toyo Ito’s design was selected. But the difficulty of building this monster in reality caused investments backing out over and over. But after conquering the obstacles, they finally broke the ground in the end of 2009.

After 5 years and NT$ 4.36 billion devoted in, the theater finally completed and the process of building the hardest architect was documented by foreign press. The theater was designated as a national degree performance center and was nominated as one of the World’s New 9 Landmarks. The first opening show “Cat Man” is performed by Ming Hwa Yuan Arts & Cultural Group.

The theater structure high 37.7 meters, 2 underground levels and 6 floors above ground. It is built with steel and concrete with the concepts of the primitive state of human livings, caves and holes. The structure consists of 58 curved surfaces, very difficult to construct. It is referred as the hardest building to be constructed. Interior designed with a large theater (2014 guests), medium theater (800 guests), and experimental stage (200 guests). Not just the main building but the surroundings is designed to correspond with Sound Cave Curved Walls.

The acoustic engineering was carefully designed. In the large theater, guests will see the round curve on the ceiling; this will reflect the sounds perfectly in every angle to every seat. A cat walk is organized on the top for maintenance purposes. The view to the stage will not be blocked in anyway. Everything is designed to what a theater may need in the best way. The exterior shapes like a tea pot during the day with the extraordinary curves. When the night falls, lightings will put the theater under the spot light.
