The Louvre said Monday (Mar 9) it was restricting entry to the world's most visited museum, as concerts were cancelled across France because of the new coronavirus.
Only people who have already reserved a ticket online, or those who normally benefit from free entry, will be allowed into the Paris landmark, the Louvre said.
The restriction comes after the vast museum was forced to close for two days last week when staff refused to work over health fears.
Pop concerts across the country were postponed or hung in the balance after the government banned public gatherings of more than 1,000 people late Sunday.
The final shows in Madonna's Madame X tour at the Grand Rex in Paris were among those cancelled.

"Up to now we have been putting back concerts to June," said Thierry Teodori, head of the 17,000-capacity Halle Tony Garnier.

The Cannes film festival – the world's biggest – has been bullish about weathering the storm.
It plans to announce its line-up for the enormous event in May as usual next month.
But the Louvre, which also attracts visitors from all over the world, was more cautious.
"Faced with Covid-19, the museum has decided to regulate entry," the museum said in a statement, adding visitors can no longer turn up and buy a ticket.
More than 9.6 million people visited the Louvre last year, most of them from abroad, with American and Chinese tourists the biggest groups.
Having taken a huge financial hit during a record-breaking French transport strike which left Paris theatres empty at the turn of the year, the virus could be catastrophic for the entertainment industry.
