National Taichung Theater

Toyo Ito designed the Taichung theatre around a geometry he called the Sound Cave: fifty-eight curved concrete shells joined into a continuous lattice so that walls become ceilings and floors without a right angle anywhere, which took years to work out how to build. It opened in 2016 with three auditoriums, and the public areas, a rooftop garden and a cafe are open to anyone. Standing in the foyer is the point as much as any performance.

What you actually see

• The curved shells - fifty-eight concrete surfaces joined without flat walls or right angles.
• The public foyer - the interior lattice, open to walk through without a ticket.
• The rooftop garden - a terrace above the building with a water feature.
• The three halls - the grand theatre, playhouse and black box inside.

When to go

Year round; the building keeps daily public hours and closes on Mondays. Evenings around performances are when it is liveliest. The rooftop is best in the late afternoon.

Honest expectations

The auditoriums are only seen with a performance ticket or on a booked tour. The public areas are limited in extent. The building has had waterproofing problems that periodically close sections.
