'The Mona Lisa' (1503-06) is a popular half-length portrait and one of the most valuable paintings in the world. It is thought to be a portrait of Lisa Gherardini, an Italian noblewoman. It is housed in the Louvre in Paris, France

Where in the world are Leonardo da Vinci's other 23 known paintings?



It was recently announced that Leonardo da Vinci's Salvator Mundi will go on display at Louvre Abu Dhabi on September 18.

The long-lost, 500-year-old painting will be the first of the master's works to be in a permanent collection outside of the US or Europe. It's also the world's most expensive painting (it was recently purchased for Dh1.65 billion).

Da Vinci's paintings are so prized because they are so rare - there are only 23 other acknowledged da Vinci's around the world (but there are another eight that are still under discussion).

Scroll through the gallery above to see where you will find the other 23, and what they look like.
