The Alfama (Portuguese pronunciation: [aɫˈfɐmɐ]) is the oldest neighborhood of Lisbon, spreading on the slope between the São Jorge Castle and the Tagus river. Its name comes from the Arabic Al-hamma (الحَمّة), meaning "hot fountains" or "baths". The district includes the freguesias (parishes) of São Miguel, Santo Estêvão, São Vicente de Fora and part of the two streets, "Freguesia da Sé: Rua do Barão" and "Rua São João da Praça". It contains many important historical attractions, as well as an abundance of Fado bars and restaurants.
The Rua do Barão is one of the streets of the Freguesia da Sé, which begins at the Rua São João da Praça (where once stood the Door of the Alfama) and ends at Rua Augusto Rosa (at the Cathedral's walls). The toponym "Rua do Barão" is because João Fernandes da Silveira, the first Baron of Alvito, minister of Portuguese kings Dom Afonso V and Dom João II, lived here.
