The Porta da Vila is the city's main gate. It consists of two low, staggered gates to prevent a direct cavalry charge, as was often the case with Gothic Portuguese castles. Between the gates is a small balcony that served as a prayer room, with beautiful blue and white tiles (azulejos) from 1740 depicting the Passion of Christ. Street performers often play there because of the acoustics.
