Construction on La Sagrada Familia began in 1882 yet the building is still under c-onstruction today, a full 130 years later. The architect, Antoni Gaudi, has infused many different forms of geometry throughout the whole interior and exterior of the basilica, employing elements such as the hyperboloid, ellipsoid and his self created double twisted column. Throughout La Sagrada Familia there are many visual references to aspects of nature such as the resemblance between the buildings columns branching out towards the ceiling to the anatomy of a tree. Gaudi's Sagrada Familia has to be my favourite piece of architecture purely because it is filled with many visually interesting features.
