On the night of October 20, in the city of Langres (Haute-Marne department, France), the “Denis Diderot House of Enlightenment” museum, dedicated to the life and legacy of the French philosopher of the Enlightenment, was robbed, RBK reports.

The incident occurred just hours after a high-profile robbery at the Louvre in Paris. Museum staff discovered the front door had been forced open and a display case smashed on Monday morning. The thieves stole a collection of 1633 silver and 319 gold coins minted between 1790 and 1840. The value of the stolen coins is estimated at approximately 90 thousand euros. The collection was discovered in November 2011 during renovations.

The thieves took advantage of the museum's closure on Mondays. Other exhibits remained untouched.

Earlier, on October 19, nine items from the Napoleon and Empress Josephine jewelry collection were stolen from the Louvre in Paris. Damages from this theft are estimated at 88 million euros.

The Louvre reopened to visitors only on October 22, but the Apollo Gallery, from which the jewels were stolen, remains closed.

This incident was part of a series of attacks on French museums since early September 2025. In mid-October, the Jacques Chirac Museum was robbed twice, and in September, three pieces of Chinese porcelain, designated a national treasure, disappeared from the National Museum in Limoges.

The French Ministry of the Interior has announced increased security measures for all museums in the country.
