"Cathedral of Barcelona While the unfinished Sagrada Familia is perhaps Barcelona ’s most famous church, its cathedral is Santa Eulàlia, a Gothic church constructed between the 13th to 15th centuries. Its neo-Gothic facade was built over the original exterior in the 19th century. The rooftop features a variety of gargoyles inspired by real and mythical creatures. Salute Barcelona’s co–patron saint, Eulàlia, the cathedral’s namesake, in the crypt, and then move on to the cloisters where 13 white geese frolic in a 14th-century fountain."
