The Louvre Museum in Paris, where thieves carried out a daylight heist stealing jewels from the Apollo Gallery on Sunday.

A meticulously planned robbery at the Louvre Museum in Paris has left French authorities searching for answers after a group of thieves disguised as construction workers escaped with a collection of jewels once owned by Emperor Napoleon and his wives. The theft, which took less than seven minutes, has drawn global attention to security lapses at one of the world’s most renowned museums.

The heist occurred early Sunday morning, just before the museum opened to the public. Investigators say the thieves arrived in a small truck equipped with a mobile freight elevator that allowed them to reach a second-floor window in the Apollo Gallery, home to France’s royal and imperial jewelry. Using an angle grinder, they broke through the glass, smashed display cases, and fled on motorbikes before police arrived.

Officials confirmed that eight items of immense cultural and historical value were stolen, including diadems, brooches, necklaces, and earrings from the collections of Empress Marie-Louise, Queen Hortense, and Empress Eugénie. Among them were a sapphire diadem and an emerald necklace from the Napoleonic era. A ninth piece—Empress Eugénie’s crown—was dropped during the escape and later recovered, damaged, outside the museum.

French President Emmanuel Macron condemned the robbery as an attack on national heritage and vowed that the jewels would be recovered. Culture Minister Rachida Dati described the operation as “precise and professional,” saying the thieves appeared to know the museum’s layout and timing in detail. The Paris Prosecutor’s Office has opened an investigation into aggravated theft by an organized criminal group.

Forensic teams recovered tools including angle grinders, a blowtorch, gloves, and a walkie-talkie from the scene. Authorities are reviewing hours of security footage and examining the truck and motorbikes used in the escape. Video obtained by French broadcaster BFMTV appears to show one suspect attempting to access a jewelry case moments before the alarm was triggered.

Experts say time is critical to recovering the jewels intact. Art recovery specialist Christopher Marinello said professional thieves often dismantle or alter stolen pieces to conceal their origins. “They’ll re-cut the stones and melt down the metals,” he said. “Once that happens, the heritage value is gone forever.”

The Louvre, which draws about 30,000 visitors a day, was closed following the theft to allow forensic work inside the Apollo Gallery. The incident comes amid reports of crowding and understaffing at the museum, with unions warning that stretched resources have created vulnerabilities. Staff walkouts earlier this year cited concerns over safety and security as visitor numbers returned to pre-pandemic levels.

Jewelry historian Nathalie Abbou Vidal described the stolen items as irreplaceable artifacts tied to France’s cultural identity. “These jewels are not just objects of beauty,” she said. “They carry centuries of history.”

As investigators trace leads across Paris and beyond, the theft has reignited debate over the protection of cultural treasures. For the Louvre, it is a sobering reminder that even within the walls of the world’s most famous museum, priceless works of art remain vulnerable.
