Nested in the heart of the administration and culture district of Sanmen County, Sanmen Theatre is a multi-performance venue where users’ experiences and social participation are priorities. Functions include a 1000 seats auditorium, a cinema, a conference hall, and exhibition spaces. The irregular form of the facade, made up of light golden aluminum panels and glass curtain wall, created a powerful visual impact. It not only indicates the golden coast line and the famous Sanmen fresh crab in culture aspect, but also shows a sense of unconventional open art space.
