It’s best known as “Rua Augusta Arch” but its main façade faces Praça do Comércio. It’s a triumphal arch designed in 1775 as a gateway to the city, but the version seen today dates from a century later, 1875. Sculptures at the top represent Glory crowning Genius and Valor. Below them are images of national heroes Vasco da Gama, the Marquis of Pombal, Nuno Alvares Pereira and Viriato.
