Barcelona's celebrated buildings reward more than a façade photograph. At the Sagrada Família, columns, light and the sense of an interior landscape create a different experience from the external skyline. A wider city walk makes it possible to compare this with other architectural approaches.
Book a precise interior visit where necessary, then group the rest of the day by neighbourhood. Do not assume optional towers are included in a standard ticket.
