Notre-Dame Church

Highlight • Religious Site

Originally a simple oratory of a pilgrim's house, it became, over time, the main church of Tonnerre. In the 11th century, the Hôtel-Dieu Notre-Dame was a modest house welcoming pilgrims on the road to Saint-Jacques. It has a small chapel dedicated to Mary. Over the centuries, the oratory grew and gained in importance. It becomes parish priest, parish then deanery. It was in the 16th and 17th centuries that the monument took on the face we know of it with its high tower surmounted by the inscriptions "Jésus Maria Ave Gracia" and the initials CHC, for Charles Henri de Clermont, Count of Tonnerre and great patron.

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.
