Architecture can be curvy and abstract

No right angles. No straight lines. Abstract. Bright colors. Curves. Round edges. Nature inspired. It's hard to believe these words describe architecture, but when you interpret Antoni Gaudí's work see how far you can get without using them.

Other than the tapas, wine and sangria, Casa Batlló was one of the highlights of Barcelona.

Barcelona's Barri Gòtic or Gothic Quarter

It's one of the sentences you will hear when someone talks about their trip to Barcelona. "The architecture was amazing."

You can see that some of the buildings were built during medieval times by the massive stone walls, pointed arches and spires and skeletal stone structures. Underneath this bridge are skeleton heads carved from stone.

I chose this picture so you can see how intense the light is when it glares down the alley on the left side. And only vertical light will hit this street, so it gets sun from about 10am-4pm. If you want uniform light get there early in the morning or later in the evening.

Also this picture gives you a good idea of how easy it is to get lost. If the sun was behind the clouds, it would be hard to know which way is north. But for now just imagine walking down the street marveling at all the intricate details!
