MUSAC — the Museo de Arte Contemporáneo de Castilla y León — is one of the most architecturally striking contemporary art museums in Spain. Opened in 2004, the building by Tuñón and Mansilla is sheathed in a mosaic of coloured glass panels whose palette references the medieval stained glass of León Cathedral, creating a visual link across the city between its most famous medieval building and its newest cultural institution.
The collection spans video, installation, photography, and new media, with a focus on work produced after 1992. Temporary exhibitions rotate regularly and tend to be more adventurous than the usual regional museum fare. Located in the newer part of the city, about a 15-minute walk west of the old quarter. Closed on Mondays.
