Even on a tight schedule, Walt Disney Concert Hall earns the hours.
Allow 20-60 minutes.
Gehry's sculptural steel sails are one of LA's great pieces of architecture, free to admire from outside and via a self-guided exterior/lobby audio tour. To experience what it's actually for you need a concert ticket; otherwise it's a striking 20-minute architectural photo stop, with a hidden rooftop garden many visitors miss.
