The Louvre reopened after closing for 4 months due to the coronavirus. Here's what the first day back looked like.

• The Louvre museum in Paris opened its doors on July 6 after closing for nearly four months due to the coronavirus.
• The world-famous art museum, which houses the Mona Lisa, has opened up 70% of its massive collection to visitors, and will now require patrons to wear a mask and make online reservations beforehand.
• In pre-pandemic times, the Louvre usually attracts 50,000 people a day. But now, the museum staff expects only between 4,000 and 10,000 visitors a day.

Paris's iconic Louvre museum reopened for business on Monday after being closed for nearly four months due to the coronavirus pandemic.

As the world's most visited museum, the Louvre is famous for housing Leonardo da Vinci's Mona Lisa painting and typically receives up to 50,000 visitors a day. But now, only 4,000 to 10,000 people are expected to visit the attraction daily, NPR reported.

On Monday, visitors were welcomed back to the museum with a new set of guidelines. Patrons must wear a face mask, can see a more limited collection than before, and must socially distance.

Here's what the first day back looked like.

Last summer, around 70% of the Louvre's visitors were tourists. The museum's director, Jean-Luc Martinez said he believes the museum attendance will be down by 20% or 30% this summer due to a lack of tourism in France.

Because of this, some tour guide workers held a protest outside of the museum in order to criticize a lack of support given to workers in the tourism industry.

A bulk of tourists used to come from the US. But since Europe has barred Americans from traveling overseas, the museum is hoping to attract more Parisians to the Louvre instead.
