Each structure can host at least two events simultaneously. The National Theater contains a smaller Experimental Theater and the National Concert Hall holds a more intimate Recital Hall. Outdoor performances can be staged simultaneously on the square. The pipe organ by Flentrop Orgelbouw in the National Concert Hall was the largest organ in Asia at the time of its installation in 1987. Both structures house art galleries, libraries, shops, and restaurants. The National Theater houses a Performing Arts Library and publication offices for Taiwan's "Performing Arts Review".
