La Ribera was the medieval city's money — the merchants, the docks, the guilds — and El Born at its heart still feels like a place that knows it. Two and a half kilometres of palaces, one extraordinary church, and a long afternoon's worth of bars.
Start at the Basílica de Santa Maria del Mar, the people's cathedral, raised in fifty-odd years by the men who worked the port. The columns stand far apart and the whole interior is built to let light move. From there, up the Passeig del Born to El Born Centre, where the old market's iron roof now shelters the streets Felipe V destroyed in 1714 — you walk above them on a gangway.
Then Carrer de Montcada, a street of merchant palaces, one of which holds the Museu Picasso and the work he made before the name meant anything. Book ahead.
End the way the barri does — a glass of vermut in a bar off the passeig, standing at the counter. Barceloneta and the harbour are ten minutes south when you are ready.
