The Church of Saint-Martin originally dates from the 11th and 12th centuries, but was remodeled and restored in the 17th century.

Good alternative to the road. It's steeper, more rocky and forested, and there are several small streams along it, so it's much nicer to connect Géovreisset and the Forge district on foot.

Very bucolic. There is a small waterfall at the top of the clearing. Too bad the highway passes right next to it...

Superb view, just a bit spoiled by the highway and factories. The path to come from Geovreisset is enchanting (it's a small trace on the ridge, in the undergrowth)
