The very first cathedral on this site was built in the 4th century. Archaeological excavations uncovered a basilica with three naves, separated by two rows of marble columns. Sadly, four centuries later, it was partially destroyed during the Moorish invasion, when much of Barcelona was set ablaze. In 1046, a new cathedral was commissioned in the Romanesque style, reflecting the dominant architecture of the time. Then, in 1298, construction began on the current cathedral, dedicated to the Holy Cross and Saint Eulàlia, spurred on by the bishop and King James II of Aragon. The building took 150 years to complete, with final touches added in the early 20th century. Its grand neo-Gothic façade was inspired by original 15th-century plans.
