Probably one of the most photographed panoramas in Lisbon, the view from the Miradouro das Portas do Sol Observation Deck takes in the São Vicente de Fora Monastery, overlooking the old district of Alfama, the Igreja de Santo Estêvão and the Tagus River. With a harmonious mix of pastel-hued period buildings with red-tiled roofs tumbling down to the waterfront, Alfama is one of the best-preserved parts of the Portuguese capital.
