Barcelona is the second largest city in Spain. Ninety percent of the visitors are fans who come to the planetary court. Even if they are ball blind, they haven't seen a complete football match [snickering] so far. It's interesting to worship the architecture of Anthony Gaudi, the Spanish architectural genius. The Bartro House is an apartment building. On Gracia Street in 1907, Gaudi completely renovated the original building and made it full of magic. Gaudi's design was inspired by the story of a warrior killing a dragon: a beautiful princess trapped in a castle, and the hero of Catalonia, Saint George, fought with his sword to save the princess and the dragon. The dragon's blood turned into a bright red rose, which St. George dedicated to the princess. So every design of this house has a special meaning. The cross-shaped chimney represents the hero. The scaly vaulted roof is the back of the dragon, while the colored glass and the balcony with unique conception are masks.
