The Bellesguard Tower, designed by Antoni Gaudí, is deeply linked to Catalonia’s medieval past. Built on the site of the former residence of King Martin I (Martí l’Humà), the last monarch of the House of Barcelona, the tower reflects Gaudí’s reading of history. Influenced by the Gothic Revival ideas of Viollet-le-Duc, Gaudí reinterpreted medieval forms with symbolic elements and advanced structural techniques. A visit to Bellesguard offers a unique insight into Gaudí’s lesser-known work and its connection to both Catalan heritage and 19th-century architectural thought.
