Designed by world-renowned architect Yoo Kerl, Tri-bowl was built as a major facility for the '2009 Global Fair & Festival Incheon' and is the world's first inverted shell structure, which won the Grand Prize in the public sector of the Korean Architecture Awards. The TRIBOWL circular performance hall, a space surrounded by warm, wood-grained birch panels, is Tri-bowl's signature space, offering audiences a special artistic experience that encompasses both sight and sound.
