With mysterious alleys and side streets that gather houses, people and stories, Alfama is known for its restaurants and Fado places, as well as the Santos Populares celebrations. Born in Lisbon, Fado soon became a national song and is now known all around the world. Sung by a Fadista (Fado singer) backed by the Portuguese guitar, it is destined to be sang until the voice hurts. In Alfama, the beauty and sadness, such as Fado and Jazz, are neighbors. The view at the Miradouro de Santa Luzia extended over the rooftops and the hill of Castelo de São Jorge, patron saint of the knights and the crusades, provides one of the most beautiful views over the city. The Sé Catedral de Lisboa is breathtaking, with its towers and Romanesque façade. At Feira da Ladra (Flee Market) on Tuesdays and Saturdays, one can find unexpected and original pieces, among antiques and bric-a-brac.
