On August 21, 1911 Leonardo da Vinci’s Mona Lisa was stolen when Vincenzo Peruggia slipped the small 76-by-53-centimetre painting out of the Louvre underneath his smock. The 16th-century Florentine beauty wasn’t discovered missing until the next day as the Louvre had been closed to the public.

Peruggia was caught two years later. He had been motivated by a desire to return the painting to its homeland in Florence, Italy, where it was located.

Today, millions of people visit the Mona Lisa at the Louvre in Paris each year to catch a glimpse of her enigmatic smile.
