Tips

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.

A real must-see - this round wash house around a turquoise green source is unique in its kind and well worth the detour.

The deep basin of the karst spring with the historic washhouse around it is, in my opinion, the main attraction in Tonnerre. Depending on your perspective, when the sun is shining you will see deep turquoise water in front of you. Plus the rushing of the water. You can also just sit here for a while and enjoy.
When we visited the spring on a Friday morning, there was surprisingly little going on.
