Tonnerre is a small village with character nicknamed "La petite Venise bourguignonne". To see among others: the perpetual waters of the mysterious Fosse Dionne, the Saint-Pierre Church, the Hôtel Dieu and its garden of medicinal plants, the vineyard hillsides producing in particular Bourgogne Epineuil.

Fosse Dionne and the town of Tonnerre

Highlight • Historical Site

The Dionne pit is a karst spring known as the Vaucluse source. It is in fact a resurgence located in the city center of Tonnerre. His presence is at the origin of the very creation of the city. It is fed mainly by the infiltration of rain in the neighboring limestone plateau. The Dionne pit is remarkable for its flow rate with an average of 300 liters per second. Its underground network extends to more than 40 kilometers, and we still do not know its depth. Access to the source is free. For your stay in Tonnerre, I suggest the excellent hotel-restaurant l'Abbaye Saint Michel which nicknames itself "stage boudoir".

Fosse Dionne

Highlight • Natural Monument

The Dionne pit is a karst source called the Vauclusian source, located in the city center of Tonnerre. It is fed by the infiltration of precipitation into the surrounding limestone plateau as well as by the losses of at least one river. The Dionne pit is remarkable for its flow and the size of its hydrogeological network which extends to more than 40 km.

His presence is at the origin of the creation of the city of Tonnerre. An elaborate washhouse was built around the spring in the 18th century.

Burgundy Canal

Highlight • Other

A long ribbon of water crossing the countryside for 242 kilometers: here is the Burgundy Canal, which connects the Yonne to the Saône and Migennes to Saint-Jean-de-Losne. For some, it is the heart of Burgundy that opens up through these quiet valleys dotted with famous churches and castles.
