The Louvre museum in Paris has announced it is closing one of its galleries because of structural weaknesses.
The Campana Gallery - consisting of nine rooms which host Greek ceramics - will remain shut as engineers investigate 'certain beams supporting the floors', the Louvre said.
This announcement adds to the museum's unwelcome attention following a high-profile heist last month in which jewels worth €88m (£76m; $102m) were taken.
Criticism has focused on lax security at the world's most-visited museum in the French capital.
Four people have been arrested over the heist, but the jewels have not been recovered. In a statement on Monday, the Louvre said that structural issues in offices on the second floor - above the Campana Gallery in the Sully wing of the museum - had led to its decision.
During these investigations, the Campana Gallery... will be closed to the public as a precautionary measure, it said.
Three weeks after the jewel theft, a report was released in which the Court of Auditors criticised managers who had preferred to invest in new artworks and exhibitions rather than basic upkeep and protection of the museum.
On the day of the heist, the suspects arrived at 09:30 (07:30 GMT), just after the museum opened to visitors. They used a stolen vehicle-mounted lift to gain access and a disc cutter to crack open display cases.
Since the incident, security measures have been tightened around France's cultural institutions, with some of the Louvre's most precious jewels even transferred to the Bank of France for safekeeping.
