What is the Patriarchate? What are the functions of a Patriarch? Why are there only four Patriarchs, in the Catholic Church, being Lisbon’s one of them? What is his role these days? These are some questions that you can clarify in this thematic guided tour to the Monastery of São Vicente de Fora, which houses the Museum of the Patriarchate of Lisbon. Knowing the history of this institution is also a way of knowing the history of our country.
