In the 1st century BC, the Romans settled their city near the river at the foot of the hill. Excavations have shown that the city at that time occupied the entire width of the Colostre valley. "Julia Augusta Reiorum Appolinaris" is then an important road junction linking Aix and Digne, Fréjus and Castellane. The four columns that can still be admired date from that period, isolated in the meadow, vestiges of a temple of which we do not know the god to which it was dedicated.
