Monnaie de Paris

The Monnaie de Paris (Paris Mint) is a government-owned institution responsible for producing France's coins. Founded in AD 864 with the Edict of Pistres, it is the world's oldest continuously running minting institution.
In 1973, the mint relocated its primary production to a facility in Pessac, and today the original facility in Paris, while still operational, functions primarily as a museum and is home to a collection of many ancient coins.
Building in Paris.
A Neoclassical edifice, the Hôtel de la Monnaie was designed by Jacques-Denis Antoine and built from 1767–1775 on the Left Bank of the Seine. The Monnaie was the first major civic monument undertaken by Antoine, yet shows a high level of ingenuity on the part of the architect. Today it is considered a key example of French Neoclassicism in pre-Revolutionary Paris. The building is typified by its heavy external rustication and severe decorative treatment. 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, 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.
Development.
Following a 5-year renovation project known as Metalmetamorphose, the museum at the Monnaie de Paris - known as the Musée du Conti (11 Conti Museum) - was reopened on 30 September 2017.
