Mudam
Luxembourg's contemporary art museum, built by I.M. Pei on the ruins of a fortress on Kirchberg.
Updated 20 October 2026
Mudam opened in 2006 in a building by I.M. Pei raised on the surviving foundations of Fort Thüngen, so the museum sits inside and above the old fortress arrowhead, with stone bastion walls at its base and a glass and limestone structure above. The collection is contemporary, built since the 1990s, with photography, installation and design well represented, and the programme runs changing exhibitions through the year. Pei was chosen partly because the site demanded an answer to the fortress underneath it, and the building was designed to sit within the surviving arrowhead rather than replace it.
History
The museum was first proposed in 1989, and after long dispute about the site it was agreed in 1997 to build it in Dräi Eechelen Park, joined to Fort Thüngen. I. M. Pei designed the building, which cost $100 million, and it was inaugurated on 1 July 2006 (Wikipedia, MUDAM).
