Portas do Sol viewpoint. the view of a postcard. The Portas do Sol Viewpoint is located over the Alfama district, to the left of the Santa Luzia Church. This is an amazing spot to take in all of Lisbon’s beauty, and it’s especially lovely at sunset. If you’re hoping to get a good photo of the city, this is definitely the place to go. Just be warned that it can get quite crowded, especially on weekends and during peak tourist season.
