La Monnaie/De Munt
Guided tours (available in English) of the city's federally funded, early-19th-century opera house unravel a colorful history that precedes the current neoclassical building, which was built belatedly on the orders of Napoléon, who deemed its predecessor too shabby. Unravel the secrets of its workshops behind the scenes, or stick around and catch its busy program of shows and classical concerts.
