La Pedrera is a modernist building in Barcelona, Catalonia, Spain. It was the last civil work designed by architect Antoni Gaudi, and was built from 1906 to 1912. This building is really impressive since it is extraordinary as other works of Gaudi such as Sagrada Familia, Park Guell etc.  Although all of his works are different and impressive, what impressed me most is the shape of La Pedrera because I have never seen a building with curves before. Besides the shape of it, the chimneys on the roof were also pretty different. Therefore, it is unique and visiting this building was a different experience for me.
