Château de Cornillon

Château de Cornillon, in the commune of Queige (Savoie, Auvergne-Rhône-Alpes), is what remains of a medieval hilltop fortress perched at roughly 1,018 metres on Mont Cornillon, right on the boundary with the neighbouring commune of Césarches. From its position the site commands both the Beaufortain valley and the Arly valley, overlooking the point where the Doron and Arly rivers meet.

What's the history behind the ruins?

The exact origins of the fortress are lost to time, though it is clearly ancient. The earliest documented member of the Cornillon family is Guillaume I, recorded as a witness in 1180. By 1222, the lords of Cornillon had formally recognised themselves as vassals of the archbishops of Tarentaise for the castle and its dependencies. The stronghold's active life was short-lived: in 1334 or 1335 it was destroyed by Dauphinois forces, and the castle at nearby Ugine met the same fate shortly after. Rather than rebuild on the same spot, the Cornillon lords abandoned the ruins and constructed a new fortified house at Marthod.

What will you see on site?

Enough of the layout survives to read the original plan. At the northeast stood a square keep, 11 by 11 metres with walls up to 2 metres thick, overlooking a crenellated quadrangular enclosure measuring 25 by 19 metres. The southwest approach, the most vulnerable side, was defended by a round tower 7 metres in diameter. Set apart, in a separate rectangular tower built on a small motte along the ridge, was the castle chapel - 6.70 by 9.60 metres - which likely served as the local parish church until the 13th century. Information panels at the site explain this history to visitors.

How do you get there?

The most common approach starts in the village of Queige. Follow the Tour du Beaufortain trail for about 45 minutes, then leave it for a paved road climbing to the Col de la Forclaz. At the pass, turn left towards Cornillon. The path crosses patches of bilberry bushes and narrows as it follows the ridge, passing a small pond (usually dry in summer) before reaching the ruins. The route is waymarked in yellow. Drivers can shorten the walk by taking the D1212 from Albertville towards Ugine, turning off towards Queige via the Col de la Forclaz, and parking at the forest edge known as "Forclaz," just below the pass.

When should you visit?

Given the altitude (over 1,000 metres) and the exposed ridge walking involved, late spring through early autumn is the best window, when the trail is dry and the views are at their clearest. In summer, an early start helps you avoid the heat on the unshaded ridge section.

What else should you know before going?

The panorama from the ruins takes in the Bauges massif, the Belle Etoile peak above Albertville, and Mont Charvin above Ugine. This is a destination for hikers and history enthusiasts rather than a conventional tourist site - there's no visitor infrastructure at the ruins themselves, just the landscape and the atmosphere of an abandoned stronghold.

Frequently Asked Questions

Can you drive up to the ruins? No. The final stretch is on foot only. The nearest parking is at the Col de la Forclaz, from where a marked trail leads the rest of the way.

How long does the hike take? From Queige, reaching the ruins typically takes one and a half to two hours one way, depending on pace and starting point - budget extra time for a break at the pond or the pass.

Are the ruins fenced off or supervised? No. They sit freely accessible in open mountain terrain, with no tickets or staff on site - just the interpretive panels.

Is there a loop route that includes the castle? Yes, the Queige-Cornillon loop is popular: it combines the climb to the ruins with a return via a different section of trail, taking in extra viewpoints over the Beaufortain and Arly valley.
