The Sagrada Familia church in Barcelona was designed by Antoni Gaudi to be filled with Christian symbolism and feature striking spindle-shaped towers as the "last great sanctuary of Christianity". Tibidabo Mountain offers views of Barcelona from its 512-meter peak and natural areas for recreation. The Ramblas is a long, central avenue in Barcelona lined with shops and one of the most visited places in the city. Park Güell contains amazing stone structures, ceramics, and buildings including Gaudi's colorful dragon fountain entrance.
