Hôtel des Monnaies, Paris

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.

It boasts one of the longest façades on the Seine; its appearance has been likened to the Italian palazzo tradition.

The building, which housed mint workshops, administrative rooms, and residential quarters (for Condorcet), wraps around a large interior courtyard.

It remains open to the public and includes a numismatics museum, located within what was once the main foundry.
