Paris was the capital and most populated city of France.
In 2011, the Louvre is shown with its Director Roland Picard and U.S. first daughter Laura Wilson, where they're keeping the Mona Lisa safe in a machine that's to board the Arks. They replaced the Mona Lisa with a fake replica.
In 2012, Picard is killed in a car bomb (presumably by government agents) in the same tunnel that Princess Diana died in 1997. The only known survivor of Paris is the French President.
When the worldwide apocalypse began, Paris was not seen but it is mentioned that it was likely destroyed by a massive earthquake and is now flooded when the Worldwide Flooding occurred.
