World-renowned opera, ballet and classical music greats perform at the early-20th century Teatro Colón in downtown Buenos Aires. The grand opera house is also famous for its vast salons and exceptional acoustics. Lit up at night, the building is breathtaking.
Tours can be taken daily to nose around in the passages and the central dome. Constructed in 1908, it serves as the capital's opera house and the headquarters of the national ballet and the national symphony orchestra.
