For the April 2023 vacations, the Musée en Herbe offers walks in Paris, in small groups, to discover the architecture and the works of art hidden there. Several routes are proposed for young people from 6 to 106 years old: Montmartre, the Louvre district, the Champs-Elysées decorated with Geluck's Cat or rather street-art in the 13th district of Paris. Shall we go there?
