The Hôtel des Monnaies is an 18th-century building located at 11 Quai de Conti in the 6th arrondissement of Paris, which has housed the Monnaie de Paris (the Paris Mint) since its construction. It is considered a prime example of pre-Revolutionary French Neoclassical architecture. The building is the masterwork of the architect Jacques Denis Antoine (1733–1801), who in 1765 bested Étienne-Louis Boullée and François Dominique Barreau de Chefdeville in a competition to design it. Though it was his first major civic project his design later won him admission to the Académie royale d'architecture.
