Château de Francheville

Château de Francheville is the remains of a medieval fortress perched on a rocky ridge overlooking the Yzeron valley. The fortification features polygonal walls built from granite rubble, particularly thick at certain sections where the stone rises to about 10 meters (33 feet) high.

The fortress was established between 1175 and 1200 by the Archbishop of Lyon, Renaud de Forez, who appointed a castellan to govern the surrounding lands. Over time, the site lost its military importance and gradually declined into the ruins visible today.

The fortress once served as a symbol of authority over the surrounding valley and still defines how locals view their region's past. Its ruins remain part of how people understand Francheville's medieval identity.

The ruins are on private property and can only be visited with prior permission from the owner. Visitors should contact the property holder in advance and be prepared for uneven terrain and potential structural hazards around the site.

The polygonal walls were constructed from rough granite blocks and reach exceptional thickness in certain spots, sometimes exceeding 2 meters (6.5 feet). This heavy construction reveals how strategic the location was for controlling the valley below.
