The MUSAC is the Castilla y León Museum of Contemporary Art, which is in the city of León, Spain. Designed by the architectural team of Mansilla & Tuñón, MUSAC opened its doors in April 2005 and has just received wide international recognition due to its winning in 2007 of the European Union Prize for Contemporary Architecture Mies van der Rohe Award and its participation on the exhibition On- Site: New Architecture in Spain, that the MOMA New York devoted to the most important recent architectural projects in Spain.
