At a height of 30 meters and visible for miles around, the “lighthouse of Essonne” inevitably imposes itself in the Essonne landscape. The top of the tower has to be earned, you will have to climb the 138 steps to reach it! At the top, enjoy and admire a magnificent 360 degree view of the department and much more. Indeed, if you easily admire the Marcoussis CNR and the charming town of Montlhéry, it is possible (on a clear day) to see the Eiffel Tower!

High place of the History of France, the castle of Montlhéry is mentioned from 1008 when Thibaut, forester of king Robert II raises fortifications. Its strategic position, between Paris and Orléans, made it a key issue for the Capetian kings. The first castle was destroyed between 1104 and 1107.
