Part of the early constructions, the small medieval castle is still a major attraction for children. Located two steps away from the Godefroy de Bouillon building where the sleeping rooms for the boys of Riaumont are, there are no Saturdays nor Sundays passing by without the sound of the playfull screaming and shouting. Those of you adults, and those of you who believes themselves to have become "reasonable", do not turn to mockery but rather try to remember when you were that age. "The worst of adulthood crimes is to make the children pay the price of the loss of their own childhood".
