Iconic 17th century chapel built following a vow made by the population to thank the Virgin Mary for protecting the inhabitants from epidemics and during the Thirty Years' War. It has an oval plan and is surmounted by a recently renovated dome with glazed roof tiles, a lantern tower and a bell tower. https://www.coeurdujura-tourisme.com/

The ascent to the cross is car-friendly and has steps. The GR59 may have been rerouted in the meantime, but a detour here is definitely justified. The paths on Mt Poupet are well signposted and the summit cross is highly recommended.

The views are particularly wonderful at the many paraglider take-off points on Mont Poupet. However, the location of this highlight is surrounded by dense forest and an antenna, so visiting this point is only worthwhile if you follow the path a little further north.
