The Louvre moved some of its most valuable jewels to the Bank of France, according to French radio station RTL, after a brazen daylight break-in last week exposed the famous museum’s vulnerability.

The transfer of some valuable objects from the museum’s “Apollo” room, where the French crown jewels are displayed, took place yesterday, Friday, under the escort of secret police, RTL reported, citing unnamed sources.

The Bank of France, where the country’s gold reserves are kept in a massive vault 27 meters underground, is located just 500 meters from the Louvre, on the right bank of the Seine River.

The Louvre and the Bank of France did not immediately respond to a Reuters request for comment.

Burglars stole eight valuable pieces, valued at an estimated $102 million, from the Louvre’s collection on Oct. 19, exposing security gaps as the thieves entered the world’s most visited museum by using a crane to break an upstairs window while the museum was open. The thieves escaped on motorcycles.

News of the theft caused a sensation around the world, causing reflection in France for what some saw as a national humiliation.
