10Sagrada Família, Barcelona
No list of Spanish architectural wonders could begin without Antoni Gaudí’s unfinished masterpiece. The Sagrada Família, a basilica unlike any other, is a dazzling blend of Gothic and Art Nouveau styles.
Its towering spires, intricate facades, and kaleidoscopic stained glass windows create a sense of wonder that words can hardly capture. Construction began in 1882 and continues to this day, making it one of the longest-running architectural projects in history. Standing beneath its forest-like columns feels like stepping into a surreal dreamscape.
