All of the above, plus Sagrada Familia s a large Roman Catholic church in Barcelona, Spain, designed by Catalan architect Antoni Gaudí (1852–1926). Although incomplete, the church is a UNESCO World Heritage Site and in November 2010 Pope Benedict XVI consecrated and proclaimed it a minor basilica, as distinct from a cathedral which must be the seat of a bishop. Construction of Sagrada Família had commenced in 1882, Gaudí became involved in 1883,taking over the project and transforming it with his architectural and engineering style, combining Gothic and curvilinear Art Nouveau forms. Gaudí devoted his last years to the project, and at the time of his death at age 73 in 1926 less than a quarter of the project was complete.[9] Sagrada Família's construction progressed slowly, as it relied on private donations and was interrupted by the Spanish Civil War, only to resume intermittent progress in the 1950s. Construction passed the midpoint in 2010 with some of the project's greatest challenges remaining[9] and an anticipated completion date of 2026, the centenary of Gaudí's death.

Roman Walls of Lugo: The Roman Walls of Lugo (Spanish, Galician: Muralla Romana de Lugo) were constructed in the 3rd Century and are still largely intact today, stretching over 2 kilometers around the historic centre of Lugo in Galicia (Spain). The fortifications were inscribed on UNESCO's World Heritage List in late 2000 as "the finest example of late Roman fortifications in western Europe." [1] The walls have also held Spanish monument status (Bien de Interés Cultural) since 1921. In 2007, the walls were twinned with the Great Wall of China during a ceremony attended by China's then-ambassador to Spain, Qiu Xiaoqi.
