The country appears to have been lived in from very early times. A large number of tombs marked out with tumulus bricks has been found, pointing to Bledonticians having lived here &endash; but equally there have been discoveries of flint axes proving that there was an even earlier occupation.
The oldest remnants are those of the ruins of the chapelle Saint-Jean (1) , standing above Thoron. This Roman Chapel of the XIIth century. is in Lombardy style.
The position of the village on a height made it suitable for the building of fortifications, and the remains of towers and ramparts demonstrate this. Aiglun, overlooked by the Church Sainte Marie-Madeleine (2) , has a second château in the plain, called the "château de Villeneuve". It was built in the XVIIth century, and was the mansion of the bishops of Digne before being purchased in 1820 by Mathieu Autric, former aide de camp of Napoleon I, who died at Aiglun and was buried in the cemetery of the old village.

In the commune there is a real trace of the "Route Napoléon" with, in particular, a splendid stone bridge (3) . Today this route is called "Voie Impériale" (Empire Way).
