On April 6, 2005—following a period of curatorial maintenance, recording, and analysis—the painting was moved to a new location within the museum's Salle des États. It is displayed in a purpose-built, climate-controlled enclosure behind bullet-proof glass.
There have been various examples of people trying to damage the picture;
In 1956, the lower part of the painting was severely damaged when a vandal doused the painting with acid. On December 30 of that same year a young Bolivian damaged the painting by throwing a rock at it. This resulted in the loss of a speck of pigment near the left elbow, which was later painted over.
On August 2, 2009, a "deranged" Russian woman threw a ceramic mug at the Mona Lisa, which at that point was protected by bulletproof glass. The woman was taken by police to a psychiatric infirmary and was found to be angry over being turned down for French citizenship.
