- Here stands the Castle de Chevalier, a powerful fortress from the year 1280. It"s home to Duke Roland, his family, his brave knights, and his many servants. All it needs is some children to come visit and fill in every room with their reusable stickers, from the busy kitchen to the deep, dark dungeon, and even the fields beyond. At the back of the book, children will find extra activities, including designing their own castle, coloring in a siege scene, making up jousting scenarios, spotting the misfits, and more! It"s a fun way to learn about a time long ago.
