Often referred to as “The Giant Egg,” this opera house seats 5,452 people in three separate halls. A French designer, Pau Andreu, designed the building that took six years to complete. The inaugural concert took place in 2007, six years after the start of construction.

The Giant Egg’s 151-foot (46 m) dome is 695 feet (212 m) from east to west, and 472 feet (144 m) from north to south. In order to enter the building, audience members walk through a hallway that goes under the lake.
