Montagne du Roule, Natural summit in Cherbourg-en-Cotentin, France

Montagne du Roule is a 112-metre summit of the Armorican Massif in Cherbourg-en-Cotentin, made of Armorican sandstone overlying shale. Its sedimentary layers date from the Ordovician and dip about 45 degrees to the northeast. A long, low stone fort, the fort du Roule, occupies the flat top.

The summit first held a hermitage before the Second Empire built the Fort du Roule on top of it. During the Second World War, galleries were cut through the fort, which now houses a museum of the Liberation. Armorican sandstone has been quarried on the north-eastern flank since work on the Cherbourg breakwater in the 18th century.

The Liberation Museum inside the fort displays exhibits about the German occupation and everyday life in Cherbourg during the Second World War. Visitors can see personal objects and documents from that period.

The ascent follows the Montée des Résistants, a winding road with several hairpin turns that is accessible on foot. Sturdy footwear is recommended, especially in wet conditions, as the path becomes quite steep.

The name "roule" is the local word for Armorican sandstone, the rock that forms the hill; the same term names other Norman sites such as the hill of Roule at Saint-Léger-du-Bourg-Denis and the Roule mill at Rosay-sur-Lieure. The sandstone was quarried on the north-eastern slope from the time of the Cherbourg breakwater works in the 18th century.
