This high patrician house in the Renaissance Mosan style was built in the early 17C for Jean Curtius, a rich arms dealer from the Spanish armies. Today, it houses some precious collections. Do not miss the Evangelary of Notger, ivory from around 1000, the Holy Virgin of Dom Rupert, a sandstone sculpture from the 1st C. In the Glass Museum, you will see the lovely collection of Art Nouveau and Art Deco vases (Gallé, Lalique, Daum, Val-St-Lambert).
