The National Taichung Theater is a Toyo Ito building from 2016, set in the new Seventh Redevelopment district of north-west Taichung. It is one of the most striking pieces of contemporary architecture in Taiwan — a five-storey block whose walls curve continuously inwards and outwards, forming caves and chambers rather than rooms.
There are three auditoria inside: a 2,000-seat opera house, an 800-seat playhouse, and a 200-seat black box. The lobby, foyer, and rooftop garden can all be visited free during the day, and the building is genuinely worth a trip even if nothing is on. Free guided tours run several times a day in Mandarin and occasional English.
