Louvre Tightens Security Post-$102M Jewel Heist; Grilles and Cameras to Fortify Gallery
December 23, 2025
A plan to install around a hundred cameras around the palace is underway, with installation expected to start in 2026 after the contract is signed.
There was a week-long museum workers’ strike from December 15 to 18 over working conditions and security resources, with negotiations continuing with the Culture Ministry.
The Louvre recently announced the completion of anti-intrusion measures around the museum as part of broader security upgrades.
Following a $102 million jewel theft in October, security bars are being installed on a window in the Apollo Gallery as authorities also charge all four suspects, though the jewels remain unrecovered.
The thieves gained entry by posing as workers, cut through a window, and fled within eight minutes after stealing tiaras, emerald earrings, a sapphire necklace, and other treasures.
The story is being updated as more security measures are considered and implemented at the Louvre.
Museum officials say the grille installation is slated to be completed before year’s end, with discussions continuing on securing other windows.
Experts and authorities say the new measures target previously identified security gaps and should reduce the risk of future intrusions.
The grille installation was confirmed by AFP to have begun the morning of December 23, 2025.
A mobile police post was deployed in the Cour Napoléon to remain through the holiday period and peak attendance times.
Security upgrades are being overseen by the Louvre’s chief architect of monuments historiques, with plans to secure additional windows under consideration.
