After a $20 million renovation, the Kennedy Center Opera House is about to reopen. “The Washington Opera will resume performances there in the spring. In a typical year, the Opera House has 225 performances, attended by a total of 500,000 people. The renovations included a top-to-bottom cleaning, from the sprawling Austrian chandelier to the expanded orchestra pit. New features include a maple floor on the orchestra level. The red seats have been redone throughout the hall, along with cherry trim and arm rests.”
