The historic bullfighting arena on the Plaça d’Espanya is where matadors once faced down bulls; afterwards, the bullring stood empty for years. Now people come here to fight for the best bargains. You’ll find 115 businesses and several restaurants in what might be the most unusual shopping center in Barcelona. Tip: Stop by Abrassame with its terrace and city views. Daylight filters through the dome, illuminating the interior of the building renovated by British star architect Richard Rogers. Open for shopping daily until 10:00 p.m.
