Four masked individuals entered the world-renowned museum in Paris just after 9:30 a.m. on Sunday, October nineteenth, and in under seven minutes made off with eight pieces from France’s royal jewellery collection.

The ini­tial intrusion occurred through the second-floor window of the Galerie d’Apollon, where the nation’s historic crown jewels are displayed.

The thieves used a truck-mounted basket lift to gain access, wielded a disc cutter to breach the glass, commandeered two high-security display cases and fled on motorbikes.

The French Interior Ministry described the group as ‘‘very professional’’ despite their “unarmed” status, noting the operation’s brevity and precision.

One of the stolen items was the emerald-and-diamond necklace once worn by Empress Marie-Louise, the second wife of Napoleon I. Also taken were a sapphire tiara and matching jewellery belonging to Queen Marie-Amélie and Queen Hortense, and a corsage bow of diamonds associated with Empress Eugénie.

The crown of Empress Eugénie itself was dropped during the escape and later recovered close to the museum, damaged but intact.

Authorities estimate the value of the heist at roughly €88 million (just over one hundred million U.S. dollars), yet emphasise that the greater loss lies in the inestimable heritage and historical value of the items.

The French government confirmed that the national museum collection is not covered by private insurance and that the state acts as its own insurer in such cases.

In the immediate aftermath, the museum was evacuated and closed temporarily.

French President Emmanuel Macron described the theft as ‘‘an attack on a heritage that we cherish because it is our history,’’ and pledged that the stolen items would be recovered and the authors of the crime brought to justice.

The Paris Prosecutor’s Office launched an investigation into theft by an organised gang and criminal conspiracy, assigning more than one hundred officers to the case, while interior officials say the possibility of foreign backing cannot be excluded.

The episode has cast a harsh light on security at the museum, which many unions and staff say suffers from inadequate surveillance coverage and understaffing.

Videos of the escape show the thieves descending the gallery wall via the basket lift and riding away on scooters with the jewels.

Investigators caution that if the loot is not recovered quickly it may be melted down, dismantled or its provenance erased — effectively lost to view.

With the museum reopening days later—with the Galerie d’Apollon still closed for forensic work—officials signalled an urgent acceleration of the planned security modernisation programme.

The director of the museum offered her resignation, which the culture ministry declined.

The manhunt remains active, and the recovery clock is ticking.
