Casa Mila - Too Futuristic?
This former private residence of an affluent couple was scorned upon by locals for an almost "monstrous" design. Today, a UNESCO listed world-heritage site!
It is also believed George Lucas' visit to Barcelona prior to his Star War series inspired the design of one of celluloid's greatest characters. Resemblance anyone ?!
Casa Batlló - A Marine Marvel
Park Güell - Park or Paleo-park?
The craziest looking park that I've ever been to!
