Built on the side of a cliff in a natural cirque, Saint-Marcellin, like Églazines, is a magnificent and emblematic site where humans have always adapted to nature to build their habitat. This troglodyte village thus preserves the remains of a rock fortification but also of jasses (caves converted into sheepfolds), a Caussenard house, a chapel, a bread oven...

The jasse d’Héran balm has always been visited, like many caves. The shepherds who converted it into jasse have now been replaced by nature or history lovers who have come to enjoy the place.

Balms are cavities open to the outside and more or less deep. They have been frequented since the dawn of time, first by wild animals then prehistoric men, followed by shepherds... and now by tourists. That of the Fig tree is particularly photogenic.
