Gaudi had this dream to design a 'village' filled with unique dwellings inhabited by equally unique residents.  It was never completed for reasons that are not at all clear, but the architecture was too beautiful, too exotic to throw away.  Eventually, the village's buildings became property of the City of Barcelona, and the city fathers decided to turn it into a park... Parc Guell.
