Children of all ages can pretend to be kings and queens, knights and archers.
Haut-Koenigsbourg Castle 55 km south of Strasbourg is a perfect example. It is filled with artifacts and has beautifully restored room and educational displays.
Plus, for the grownups, there is the incomparable view and the authentic medieval or Alsatian food in the restaurant serving everything. Even a snap-on tray high chair to secure the toddler.
