Argentina's national opera house, and by most accounts one of the finest in the world. The Teatro Colón opened in 1908 after two decades of construction and controversies, a grand Italian-style lyric theatre seating over 2,000, with horseshoe-shaped auditorium, seven tiers of boxes, and a stage large enough for full-scale productions of Wagner.
Guided tours of the interior run daily and are the best way to see the building if you are not attending a performance. The main auditorium, the rehearsal rooms, and the costume workshops are all covered. The Opera season runs from March to December; the ballet company performs year-round. Book ahead — the house sells out regularly, especially for the opening nights of major productions.
