Overview
Mines Paris was originally established in 1783, then closed in 1791. The museum was established in 1794, in the Hôtel de Mouchy, a former aristocratic mansion in Paris. Its head René Just Haüy described it as a Cabinet of Mineralogy "containing all production in the world and all productions of the Republic, arranged by locality." It was quickly augmented by private collections, sometimes seized by the state. Many fine additions were made in short order, and by 1814, the museum contained about 100,000 samples at the Hotel de Mouchy. During the 19th century and early 20th century, it continued to acquire high-quality collections from around the world, interrupted for several decades starting with World War II, but then resuming.

Today the museum is described as one of the ten largest mineral collections in the world, containing some 100,000 samples including 80,000 minerals, 15,000 rocks, 4,000 ores, 400 meteorites, 700 gems, and 300 artificial crystals.
