The Chiran is an imposing mountainous area settled at the edge of the Commune of Blieux. It had a pastoral mission for a long time, flocks from the lower Provence came there to graze the summer pastures. But now, since recent decades, Mount Chiran is famous for something else: the sky and the stars. The National Centre for Scientific Research in fact chose this place in 1967 for its upper-air and photometric qualities.
