In Chambord, we know "the castle", the most majestic castle of the Loire Valley. Built by François I in 1519, it celebrates this year its 500th anniversary. A wonderful anniversary for the monument and the park that surrounds it. For the splendid stone dream is in the heart of a 5,000 hectare estate. This is the place that the King chose at the time, this forest inhabited by animal species to build his residence. He had his domain enclosed by a 32 kilometer long wall that still remains. The territory thus represents the surface of Paris intra-muros.
