The Apollo Gallery at the Louvre in Paris opened to the public on Wednesday for the first time since a dramatic robbery in broad daylight. Crown jewels valued at 88 million euros (102 million dollars) were stolen in the heist.

Visitors can now walk through the majestic hall, admiring its gilded ceilings and Greek frescos on their way to the nearby Mona Lisa. However, they will not find any Crown jewels or empty display cases. The precious collections previously exhibited have been removed. The museum states that the gallery has returned to its original 17th-century ceremonial purpose.

The stolen jewels have yet to be recovered nine months after the incident. The ancient pieces once displayed will be relocated to other parts of the museum, according to Christophe Leribault, director of the Louvre. “This is also an opportunity to rediscover the splendid architecture and decoration of this gallery,” he said. Leribault took on the role of directing the Louvre in February after the former director, Laurence des Cars, stepped down following the jewel heist and a series of incidents that had eroded confidence in the leadership of the world’s most visited museum.

“That dark day when iconic pieces were taken cannot be forgotten and, indeed, I believe it should not be forgotten,” said France’s Minister of Culture, Catherine Pegard. “It was a trauma for everyone, who for days expressed shock and sadness in every language. It was a trauma for us, realizing the fragility of a place we believed unbreakable, and which, like many others, proved vulnerable.”

The security measures at the Parisian museum have been enhanced with new surveillance cameras and anti-intrusion systems. On the day of the robbery, the thieves took less than eight minutes to force their way through a window into the Apollo Gallery and steal Crown jewels worth 88 million euros (102 million dollars) from the Louvre. The weekend operation left visitors stunned and exposed significant security vulnerabilities.

Improving security is a priority in the ten-year “Louvre New Renaissance” plan, initiated last year. This plan is estimated to cost up to 800 million euros (933 million dollars) to modernize infrastructure, ease congestion, and dedicate a gallery to the Mona Lisa by 2031.
