La Sagrada Familia is a Roman Catholic basilica located in the city of Barcelona. The history of this monument began in 1874, when a local organisation decided to campaign for the construction of a church in honour of the holy family. Gaudí was not the original master builder of the church; it was in fact Francisco de Paula del Villar, a diocesan architect, who began the design and construction in 1882 before entrusting the project to Gaudí a year later. He completed his sketch in 1923, which is still under construction today. Since Gaudí's death, many other architects have taken up the project where he left off. This work of art was listed as one of Europe's must-see tourist attractions in January 2020, and is a UNESCO World Heritage Site.
Built as an expiatory temple, the Sagrada Familia was financed from the outset exclusively by private donations, as is still the case today thanks to the gifts received from the many admirers of Gaudí's masterpiece.
