Officially Praça de Dom Pedro IV, but nobody calls it that. Rossio has been Lisbon's main square since the Middle Ages — the place where autos-da-fé were held, revolutions started, and locals have met for coffee since coffee arrived in Europe. The wave-pattern cobblestones are the square's signature, and the Café Nicola on the western side is the most atmospheric place for a bica. The ornate Rossio railway station, a neo-Manueline confection from 1890, anchors the northern end.
