The Grand Duke Jean Museum of Modern Art – abbreviated to Mudam – is a museum of modern art in Luxembourg City, in southern Luxembourg. The museum stands on the site of the old Fort Thüngen, in the Clausen quarter, in the north-east of the city. First proposed in 1989 and championed by then-Prime Minister Jacques Santer, the location of the future museum was much disputed, until it was agreed in 1997 to use Dräi Eechelen Park and connect the museum to Fort Thüngen. The building was designed by Pritzker Prize-winning architect I. M. Pei, and cost $100m to build. The museum was inaugurated on 1 July 2006 by Grand Duke Jean, to whom the building is dedicated, and opened to the public the following day. The museum is directed by Enrico Lunghi. As Luxembourg had no public modern art collection and the museum budget did not allow acquiring a modernist collection, the museum focused on contemporary art – its permanent collection includes works by 100 artists, including: Andy Warhol, Bruce Nauman, Julian Schnabel, Thomas Struth, and Daniel Buren. In its first year being open to the public, the museum had more than 115,000 visitors, which is a record attendance in Luxembourg.
