Immerse yourself in the Middle Ages, your children can dress up as damsels or knights at the cash desk, and walk up and down the stairs in this wonderful castle complex in the footsteps of the castle residents of the time. When your feet are tired, comfortable chairs invite you to linger while the little damsels and knights play a tournament.
