From the theft of the Mona Lisa in 1911 to the French Crown Jewels heist this past weekend, the Parisian musuem has seen some audacious crimes over the decades.

A robbery took place on Sunday morning at the Louvre Museum in Paris, resulting in its exceptional closure. Affected visitors can request a refund... Here are the steps to follow.

The museum was closed Sunday after the robbery, which was carried out by thieves using a ladder mounted on the back of a truck, officials said.

A manhunt is under way for a gang of thieves who carried out a broad daylight raid on Paris's Louvre Museum and stole jewels described as priceless. French Interior Minister Laurent Nuñez said it took just minutes for the masked suspects to carry out the burglary on Sunday morning, shortly after the museum opened to visitors.

On Tuesday August 22, 1911, the Mona Lisa was stolen from the Musée du Louvre under everyone's noses. In the early hours of the morning, painter Louis Béroud, accompanied by engraver Frédéric Laguillermie, went to the Salon Carré of the Louvre. The two artists, both regulars, were planning to sketch, as usual, a painting on display in the museum.
