Azzana is a small village of pastoral origin at an altitude of around 460 meters. It clings to a very steep slope, surrounded by forest and maquis, and is halfway between the crest of the mountain and the river.

This village is stretched lengthwise and the houses installed on a slope are large old homes in dark granite grouped around the church.

This pastoral village was founded by six families of shepherds who settled on a transhumance route between the mountains to spend the summer and the sea in winter. The shepherds stayed in the village in the spring and fall.
