Olympic Stadium.

Estadi Olímpic Lluís Companys (formerly known as the Estadi Olímpic de Montjuïc) is a stadium in Barcelona, Spain. Originally built in 1927 for the 1929 International Exposition in the city (and Barcelona's bid for the 1936 Summer Olympics, which were awarded to Berlin), it was renovated in 1989 to be the main stadium for the 1992 Summer Olympics. The stadium has a capacity of 55,926 (70,000 during the 1992 Olympics), and is located in the Anella Olímpica, in Montjuïc, a large hill to the southwest of the city which overlooks the harbour.

In 2001 the stadium was renamed after the former president of the Generalitat de Catalunya Lluís Companys i Jover, who was executed at the nearby Montjuïc Castle in 1940 by the Franco regime. – wikipedia

The Sagrada Familia.

"The Temple Expiatori de la Sagrada Família (official Catalan name; Spanish: Templo Expiatorio de la Sagrada Familia; "Expiatory Temple of the Holy Family"), often simply called the Sagrada Família, is a massive Roman Catholic church under construction in Barcelona, Catalonia, Spain. Construction began in 1882 and continues to this day.

The Sagrada Familia was designed by Antoni Gaudí (1852–1926), who worked on the project for over 40 years. Gaudi devoted the last 15 years of his life entirely to the endeavor. The project is scheduled to be completed in 2026. On the subject of the extremely long construction period, Gaudí is said to have remarked, "My client is not in a hurry." After Gaudí's death in 1926, work continued under the direction of Domènech Sugranyes until interrupted by the Spanish Civil War in 1936." – Wikipedia
