The Musée d'Art Moderne Grand-Duc Jean is Luxembourg's main contemporary art venue, in a striking glass-and-stone building by I.M. Pei perched on the ramparts of Fort Thüngen. The collection focuses on contemporary art from the 1980s onwards — strong on conceptual and installation pieces — and the temporary exhibition programme is ambitious.
The light-filled atrium is worth the visit on its own. The Mudam Café has a terrace overlooking the Three Acorns and a daily lunch menu. Closed Tuesdays.
