8La Sagrada FamĂ­lia, Spain

Barcelona’s La Sagrada Família, designed by the visionary architect Antoni Gaudí, is a marvel of modernist architecture.

Construction began in 1882, and the basilica remains unfinished, with an anticipated completion date in the coming decades. Gaudí’s design integrates Gothic and Art Nouveau forms, with towering spires, intricate facades, and a play of light and color inside the nave. Each section of the church tells a biblical story, making a visit both an artistic and spiritual journey.
