Along with Porta do Soar, Porta dos Cavaleiros is one of the few remains of Viseu medieval wall. Even though there were former defensive structures, Viseu greatest protection oeuvre was built in 1472 under D. Afonso V. reign. That defensive construction consisted of seven doors (“portas”), but only two of them have remained intact. You can get to Porta dos Cavaleiros through square Largo Mouzinho de Albuquerque along Avenida Emídio Navarro.
Right next to Porta dos Cavaleiros there is Solar dos Albuquerque and fountain – Chafariz de São Francisco, where the19th century Portuguese writer Camilo Castelo Branco has set the mortal confrontation between Simão Botelho and arrogant nobleman who courted Teresa, in his immortal literary work “Amor de Perdição”.
