Rossio Square has been a major gathering point in Lisbon for centuries. Officially named Praça de D. Pedro IV, the square was virtually destroyed in the 1755 earthquake, fire, and tsunami that devastated Lisbon. Marques de Pombal, the famed statesman who took control of the recovery and rebuilding of Lisbon after the earthquake, had a city plan developed. At the center of the plan was a rebuilt Rossio Square, connected to Praça do Comércio by two straight streets, Áurea and Augusta Streets. This area became known as the Pombaline Downtown.
I like this photo because you see the beautiful calçada portuguesa, the patterned pavement of the square, as well as catching a glimpse of two of two major landmarks of the area, the Santa Justa Lift and the Carmo Convent.
