Rougemont - Ancien donjon

The Ancien donjon of Rougemont is a set of ruined medieval castle remains crowning a hillock above the Armançon valley, in the small commune of Rougemont, in the Côte-d'Or department of Burgundy.

How to get there?

Rougemont lies about 9 km northwest of Montbard, the nearest sizeable town in this part of Burgundy, within the Montbard canton and arrondissement. The commune itself is small — barely 9.5 km² — with the Armançon river and the Canal de Bourgogne marking its southwestern edge. The castle ruins stand apart from the village, on a hillside roughly 850 metres southeast of the centre, at a spot known locally as "sous les tours" ("below the towers"), overlooking both the river valley and the RD905 road running alongside it. The easiest approach by car is from Montbard, following local roads toward Aisy-sur-Armançon and on to Rougemont.

What will you see?

The stronghold is thought to date from the 11th century, built using opus spicatum — a herringbone masonry technique typical of pre-Romanesque military architecture. It sits on an irregular motte that rises nearly ten metres above a deep surrounding ditch on its north and west sides, while the ground slopes gently down toward the Armançon to the south.

What survives today is mostly the northeastern portion of a square tower: two corner returns and a stretch of the north face, pierced by three large arrow slits at second-floor level. The east and west walls are half-collapsed, though first-floor doorways are still visible in what remains of them, while the south face has vanished entirely. The western half of the motte is now bare ground, but its shape suggests a second, matching tower once stood there — a symmetrical layout typical of the region's more important strongholds.

A history shaped by feudal politics

The earliest recorded owner is Eudes, viscount of Rougemont in 1097. In 1172, Guy de Nevers, then lord of the castle, refused to offer hospitality to the Count of Hainaut — a small episode that hints at the fortress's weight in regional feudal disputes. In 1210, Hervé de Nevers exchanged Rougemont for the Château de Grignon with Eudes III of Burgundy, pulling the stronghold into the orbit of the Duchy of Burgundy. Grazing rights over nearby pastures were granted to the Abbey of Saint-Jean-de-Réome in 1244. The castle's end came in 1411: during the war between the Burgundians and the Armagnacs, Armagnac forces occupied it, and the Count of Nevers, retaking it, had it pillaged and destroyed. It was never rebuilt.

Today the ruins belong to the commune of Rougemont and have been listed on France's Supplementary Inventory of Historic Monuments since 5 September 1996.

When to visit?

Since this is an open hilltop ruin, spring and summer are the best times to visit, before the grass and undergrowth on the motte grow too high, and while longer daylight hours make the walk out and back comfortable. In autumn, the Armançon valley view gains extra colour from the changing leaves, and visitor numbers thin out noticeably. Sturdy shoes are worth packing — the approach crosses fields and meadows outside the village, and the ground can be uneven.
