This was the most impressive church visit of my entire Europe trip. It's so special and different from other churches, as it incorporates Gaudí's unique design, blending natural forms, like tree-like columns, organic curves, and nature-inspired motifs, with stunning stained glass and light. The whole visiting experience is enjoyable: once you've reserved your ticket, you can choose the audio guide language in the Sagrada Família app. The guide follows the normal visiting route, from the entrance to the exit, and you can choose between a concise or detailed version, with the estimated time required provided, so you can better manage your time. The guide also tells vivid stories, helping visitors truly understand the background and the building's inspiration. No prior research on the Sagrada Família needed. I'd highly recommend booking a timeslot after noon, so you can experience the beauty of Gaudí's design combining nature into this amazing building.
