Hello, this is a photo of the Louvre museum, and it is so big that you'll need weeks to see it completely, I'm not exagerating.
The palace of the Louvre was a royal residence during 8 centuries. It was built in 1200, but during the years it was modified and enlarged. In 1682 the kings moved to Versailles, and the maintenance of the buiding was no longer done: in consequence the building was almost destroyed in 1750. Luckily, it becames a museum and now we can enjoy it.
Saludos,
Javier
