You can walk all the way around the Upper City – a hilltop island of centuries-old buildings and cobblestone streets – atop the rectangular, tree-shaded ramparts . The Basilique Notre Dame , its towering, Italianate dome visible from all over town, is an odd structure built from 1827 to 1866. The partly Romanesque crypt was under renovation at the time of research. The nearby Château-Musée , housed in a 13th-century fortified castle, contains Egyptian antiquities, 19th-century Inuit masks, Andean ceramics and a collection of Grecian urns.
Among the impressive buildings around place Godefroy de Bouillon are the neoclassical Hôtel Desandrouin , built in the 1780s and later used by Napoléon, and the brick Hôtel de Ville (1735), with its square medieval belfry (ground floor accessible through the lobby).
