Located on the Potomac River next to the Watergate complex, Washington's premier performing arts venue (dedicated to arts advocate JFK) has nine stages and is the home base for the National Symphony Orchestra and Washington National Opera. It hosts more than 2,000 performances each year, including touring plays, Broadway musicals, and dance programs. Free performances, from Japanese koto recitals to family-friendly theater, take the Millennium Stage daily at 6 p.m. (tickets are not required). The building itself is also worth a look: There's artwork on display (gifts from other nations), an impressive bronze bust of JFK in the Grand Foyer, and panoramic Potomac River views from the building's outdoor terraces. Guided tours are available.
