Zaragoza is known both in Spain and worldwide for its stunning Cathedral of La Seo and the Basilica of Our Lady of the Pillar, whose magnificent tiled domes have been welcoming pilgrims on the banks of the Ebro River for centuries. Visitors have to pay a small fee to visit la Seo, but Our Lady of the Pillar entrance is free, so don’t miss the Holy Chapel (note that weddings and other events might take place at the temple, so plan your visit accordingly). Right next to this stunning basilica, you can explore 2,000-year-old Roman remains, including The Forum of Caesaraugusta and the Roman Theatre. After this, it’s a good idea to join Zaragoza Free Walking Tours to visit the intricate designs of the finest Moorish architecture in the Aljaferia Palace, and see the best masterpieces of the great artist Francisco de Goya. Other interesting landmarks are the Church of Santa Isabel of Portugal & San Cayetano.
