The Rossio has been Lisbon's gathering ground for some seven centuries, and its whole floor is laid in a rolling black-and-white wave. The pavers call the pattern mar largo, the wide sea, and it was laid here in 1848, block by block by hand. Two bronze fountains flank a column with Pedro IV on top, and four-storey fronts ring the square, closed at the north end by the Teatro Nacional D. Maria II.
This ground carried fairs, markets, bullfights, carnival, and the public sentences of the Inquisition. The earthquake took the buildings and Pombal rebuilt the square inside his new grid. It has never stopped being the busy end of town: commuters cross it, buskers work it, and the old cafés around it have been serving coffee to people watching all of that for a very long time. The horseshoe-arched railway station stands on the north-west side and looks nothing like a station, and just off the north-east corner standing bars sell ginjinha to a queue that never quite disappears.
