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.
