What if discovering a garden of medicinal plants could be done while having fun? A booklet-games accompanies children, from 6 years, in their visit of the garden of the Hotel-Dieu-le-Comte. They are invited to follow a playful path to discover the plants and their effects. This booklet, distributed free on request, was designed and produced by Louise Wiesel, student in Master 2 Heritage and cultural mediation as part of her curriculum at the University of Reims Champagne-Ardenne/ Campus des Comtes de Champagne. Do not hesitate to bring this booklet-game to discover with the family the beautiful garden of the Hotel-Dieu (access by the street of the City) and good visit!
