Sous les châteaux et les villes que nous connaissons, un autre monde médiéval a existé, entièrement caché sous nos pieds. Un royaume souterrain de tunnels secrets, de caves voûtées et de passages mystérieux, creusé à la main dans la terre et la pierre pour des raisons de survie, de commerce ou de guerre. Ce documentaire vous entraîne dans cet univers oublié. Découvrez les techniques ingénieuses qui ont permis aux bâtisseurs du Moyen Âge de construire sous terre sans aucune machine moderne. Nous explorerons les énigmatiques tunnels erdstall qui déconcertent encore les archéologues, les passages de fuite dissimulés dans les châteaux forts, et les redoutables sapes militaires capables de faire s'effondrer les plus puissantes murailles. Vous apprendrez comment ils prévenaient les effondrements grâce à des voûtes en pierre sophistiquées, comment ils assuraient la ventilation dans des espaces confinés, et comment ils créaient de vastes réseaux de caves qui formaient une véritable infrastructure économique sous les cités. Des cryptes sacrées abritant des reliques aux humbles abris de paysans, chaque structure témoigne d'une facette méconnue de la vie médiévale. Ce voyage remet en question les idées reçues sur les capacités technologiques du Moyen Âge et révèle un niveau de savoir-faire souvent négligé. Plongez avec nous dans les profondeurs de l'histoire pour redécouvrir l'ingéniosité et les secrets du monde souterrain médiéval.
