Praça do Comércio
From the Pombaline reconstruction dates the Bandeira Arch ("Arco da Bandeira"), a building at the south side of the square with a baroque pediment and a big arch that communicates the Rossio with the Sapateiros Street. The Rossio became linked to the other main square of the city, the Praça do Comércio, by two straight streets: the Áurea and the Augusta Streets.
