La Pedrera’s Essential visit includes courtyards, an apartment, the attic and rooftop. The attic houses a Gaudí exhibition; the apartment presents historic domestic life. On the roof, chimneys and ventilation towers become sculptural forms with real functions.

It beats Batlló by connecting explanation, rooms and roof. The Palau de la Música takes second for the unity of its concert-hall interior. Check roof access and mobility information before booking: the operator describes the visit as partially accessible, not step-free throughout.
