Mona Lisa is one the most famous painting of the Louvre, attracting around 8 million visitors a year!
She represents Lisa del Giocondo, a 16th century noblewoman from Florence.
The portrait was commissioned by her husband, a rich silk merchant and politician.
She's particularly famous for her enigmatic smile and her stare - which seem to follow the viewer around the room.
But did you notice that she doesn’t have any eyebrows?
They were removed in the 16th century, when it was fashionable to shave them off!
Da Vinci brought the painting with him when he moved to France, and kept it for himself until his death.
It was then bought by king Francis I and was part of many famous private collections.
Both Louis XIV and Napoleon's wife Josephine had it in their apartments.
