Park Guell is a park designed by Gaudi, that consists of complex architectual elements. It was built in the years 1900 to 1914. Interestingly the park was originally a part of a commercially unsuccessful housing site. It was a project that Gaudi and his patron Guell were working on for the rich / upper class. Later on it was turned into a public park. Gaudi's Style is evident through the designs of the park. One of my favorite parts were the mosaic-like benches which he made of broken ceramics. Gaudi actually intentionally broke different kind of ceramics such as plates and cups, and used the broken pieces to create different elements of the park.
The architect finds most of his insperation through nature, and you can see that in many parts of the park. He created paths that were made in such a way that if you were standing under a huge ocean wave. There was also a part of the park that was covered by a ceiling, and when you stood beneath it and looked up, it seemed as if you were standing in the ocean looking up at the surface. Gaudi didnt use a lot of straight lines in the park, you could see curves and waves, I assume relating to the ocean. Even his benches were made in a wave-like shape. Funnily, to design the curvature of the bench surface Gaudí used the shape of butts left by a naked workman sitting in wet clay.
