Le Mans - Automobile Museum Musée de l'Automobile

Just south of Le Mans are the famous car- racing circuit, 13.5km/5.5mi long, used in the Le Mans 24-hour race ("Les 24 Heures du Mans") and the Circuit Bugatti, a 4.25km/2.5mi long training circuit. There is an interesting Automobile Museum with 150 vehicles, including cars dating from 1914 and racing cars of 1920-1949.
This is more than just a car race it's a festival.

There are midway rides, food of every possible nationality, with things to do for the entire 24 hours.

Racing for 24 hours is much tougher than racing 24 times for one hour. The strain on the machines, the drivers and the mechanics is enormous, which invariably leads to high drama. It's a motor sport event that every racing fan must see at least once in his lifetime. The race is held in June on roads that are used by the public the rest of the year.
