Milwaukee Art Museum
The wings of the roof are an art installation and open like this at 10:00 AM
The Museum’s signature wings, the Burke Brise Soleil, form a moveable sunscreen with a 217-foot wingspan. The brise soleil is made up of 72 steel fins, ranging in length from 26 to 105 feet. The entire structure weighs 90 tons. It takes 3.5 minutes for the wings to open or close. Sensors on the fins continually monitor wind speed and direction; whenever winds exceed 23 mph for more than 3 seconds, the wings close automatically.
