You will be unable to ignore the amount of religious architecture that you will come across in Lisbon. One such must-visit destination is that of the Church of São Vicente of Fora. Located in Lisbon, this Augustan church was commissioned by Afonso Henriques. It was a monastery outside the city, which was dedicated to St Vincent, the main saint of Lisbon. After the church was built, St Vincent’s remains were returned and housed there.
