Set in the Chevreuse valley, Breteuil is one of the most charming castles in the Île-de-France region. Built at the turn of the 17C and enlarged in the 18C-19C, it has been in the same family for three centuries. The superb estate is a hit with young and old alike, who come to revise their French history (display of wax models), watch re-enactments of Charles Perrault's famous fairy tales, admire the formal gardens and stroll through the castle's romantic grounds.
