Spanish museum architecture has experienced a marked upturn since the 1990s, helping even small towns off the tourist beaten track to acquire extraordinary museum buildings. This is expressed most visibly without a shadow of a doubt in Frank O. Gehry`s Guggenheim Museum in Bilbao. But there are not just the international stars who have contributed to this success. Spanish architects in particular have designed unique museums that have changed the look of whole towns. One example is the Museo de Arte Contemporáneo de Castilla y León in León in Castille, built by the Madrid architects Mansilla+Tuñon.
