In the heart of the city of Palma de Mallorca stands the magnificent 14th century cathedral Catedral-Basílica de Santa María de Mallorca, also known as La Seu. It's the most emblematic building in Mallorca’s capital - it’s a must-visit. Designed in the Catalan Gothic style but with Northern European influences, it was begun by King James I of Aragon in 1229 but only finished in 1601. In 1901, Antoni Gaudí was invited to take over the project. While some of his ideas were adopted – moving the choir stalls from the middle nave to be closer to the altar, as well as a large canopy – Gaudí abandoned his work in 1914 after an argument with the contractor. The planned changes were essentially cosmetic rather than structural, and the project was cancelled soon after.
