Basilica of the Sagrada Família I Carrer de Mallorca, 401, Barcelona
Gaudí took over the direction of this work from a neo-Gothic plan that had already been built by Francisco de Paula del Villar, with whom he had begun to collaborate while studying at the school of architecture. During the almost forty years he worked there, until his death, he designed the apse and façade of the Nativity, delimited the perimeter and crowned one of the bells, Sant Bernabé. The design of the building takes Gaudí's geometric and structural proposals to their final consequences.
