1Casa Batlló
Gaudí's undulating apartment block with a dragon-scale roof and mosaic balconies. You'll stand in the courtyard (free) to see the facade, or book a ticket to walk inside the flats. It's the drama-queen starter to understand his style. A 2-minute walk from Passeig de Gràcia metro.
Insider tip: Skip the queue: enter before 3 PM or after 6 PM. The interior's worth the ticket if you have time, but the street view alone tells the story.
