Guests meet their guide in front of the KFC on Avinguda de Gaudi and begin with a reading of the Nativity Facade, the only facade Gaudi supervised directly, where stone carvings depict scenes from Christ's life alongside plants, animals, and insects drawn from nature. The tour continues to the Passion Facade, sculpted by Josep Maria Subirachs after Gaudi's death, where the guide decodes the symbolic narrative of the crucifixion and a mathematical magic square hidden in the stone. Throughout the walk, travelers gain context on the Eixample district's 19th-century grid design and its place in the story of Catalan Modernism. The tour closes with an overview of the ongoing construction and the planned Glory Facade. Tickets are not included.
