profonde source karstique et un lavoir du XVIIIe siècle au cœur de Tonnerre.","La Fosse Dionne est une source karstique au centre de Tonnerre, qui jaillit dans un bassin de pierre circulaire encadré par un lavoir du XVIIIe siècle. L’eau remonte d’une galerie noyée dont l’entrée est visible depuis le bord. Des plongeurs l’ont explorée à de grandes profondeurs, et la ville s’est développée autour d’elle.",[511,512],"À l’époque gallo-romaine, la source alimente l’agglomération du plateau qui la domine, et la ville actuelle s’est construite autour d’elle. Son nom viendrait de Fons Divina, la source divine, ou de Divona, déesse celte des sources. En 1758, Louis d’Éon, père du célèbre chevalier d’Éon, la fait aménager en lavoir, avec un bassin de 14 mètres de diamètre sous un toit en demi-cercle. Elle est protégée au titre des monuments historiques depuis 1920.","Le réseau souterrain qui s’étend derrière la source dépasse 40 km, et des traçages par colorant montrent qu’une partie de son eau provient d’une rivière qui se perd dans un gouffre à environ 43 km de là. Des plongeurs explorent pour la première fois la galerie noyée en 1955. Après des accidents mortels en 1962 et en 1996, la plongée est interdite, puis strictement encadrée, comme aujourd’hui. En 2019, un plongeur atteint la profondeur record de 79,5 mètres.","Suivez les vieilles rues jusqu’au bassin rond à l’eau limpide, au fond duquel s’ouvre, sombre, l’entrée de la galerie noyée. Tout autour court le bac de pierre où travaillaient autrefois les lavandières, à l’abri du toit incurvé. Des foyers disposés sur le pourtour servaient jadis à produire la cendre utilisée pour la lessive. C’est un lieu calme, un brin mystérieux, et une courte halte entre l’Hôtel-Dieu et une dégustation à Chablis.","Comptez 20 à 30 minutes. La source se trouve à quelques minutes à pied de l’Hôtel-Dieu, au centre de Tonnerre, à environ 1 h 45 de Beaune et à 20 minutes de Chablis. La plongée y est strictement encadrée : contentez-vous de l’admirer depuis le bord. Renseignez-vous auprès de l’office de tourisme local pour les horaires des visites guidées.","La Fosse Dionne débite habituellement environ 300 litres d’eau par seconde, mais le 15 mars 2001, en crue, son débit a atteint 3 000 litres par seconde.","Fosse Dionne, Tonnerre : la source et son lavoir","Source karstique profonde qui remonte dans un lavoir du XVIIIe siècle, au centre de Tonnerre.
