Museo Vostell Malpartida is one of the more unusual museum experiences to be had in Spain. Outside the museum (actually the museum is both inside and outside) a Mig-21 fuselage stands over 100 feet high like a contemporary totem pole with old cars

sandwiched at intervals all the way up.

Another car is carved out of solid rock, blending in strangely with the granite boulders strewn all around the blue reservoir. Inside what was a former wool-washing complex transcendental

acrylic paintings hang on walls, as do 20 motorcycles and other conceptual artworks, including half a human torso in polyester.

Another car is surrounded by a wall of baguettes. The vanguard museum is the brain-child of the Spanish-German Wolf Vostell, a renowned contemporary artist of the post-war era who is credited with the technique known as dé-coll/age and who was an instigator of the video-art and Fluxus movements, the latter of which is haracterized by nothing in particular except the whim of the artist.

Upon discovering this strange natural landscape in the 1970s, Vostell declared it a “Work of Art of Nature.” He then set about the task of manipulating the space as a showcase for his own work and that of other artists who were not only pushing the boundaries of art but subverting them altogether.
