Casa Batllo is my favorite building in Barcelona. Make that Europe. Who knew you could turn a watercolor painting into an edifice? If I could plan my wedding again, maybe this would have to be the venue. I fell in love with this place my junior year in college when I spent a semester abroad in Barcelona. The night before my return to the States, I had to run back to Paseo de Gracia and look at it one more time. It was all lit up when I arrived, but then, just as I was about to leave, it went dark. Coincidence? I don't think so.
