The Cathedral of the Holy Cross and Santa Eulàlia, or simply the Barcelona Cathedral, is the Gothic cathedral and seat of the Archbishop of Barcelona. Its construction began in 1298 on the site of an ancient Roman temple and took more than 150 years to be completed. Located in the centre of the historic Gothic Quarter of Barcelona, the cathedral is dedicated to the martyr Santa Eulàlia – the patron saint of Barcelona – who was tortured to death in late Roman times. Her corpse is buried under the main altar. Be sure to climb to the roof for a nice view of the city, and don't forget to visit the serene and beautiful courtyard, which is occupied by thirteen white geese representing the years of Saint Eulalia's life before she was martyred.

Antoni Gaudi's ambitious project remains, as of today, unfinished, which by no means takes away its massive popularity, receiving nearly 4.5 million visitors every year. The Basílica de la Sagrada Família, or simply La Sagrada Família, is a large unfinished Roman Catholic minor basilica, considered the best example of Modernist architecture. Meticulously crafted to embody the Christian faith through composition, sculpture, and individualistic, offbeat design, this masterpiece is the kind of attraction that has to be experienced to be believed. Guided and audio tours are available in several languages.
