The Royal Theatre of La Monnaie is an opera house in central Brussels, Belgium. The National Opera of Belgium, a federal institution, takes the name of this theatre in which it is housed—La Monnaie in French or De Munt in Dutch—referring both to the building as well as the opera company. As Belgium's leading opera house, it is one of the few cultural institutions to receive financial support from the Federal Government of Belgium. Other opera houses in Belgium, such as the Vlaamse Opera and the Opéra Royal de Wallonie, are funded by regional governments.
