Someone asked me once which was my favorite monument in Lisbon. It is probably the city's aqueduct. I like that it distributes an essential element for life and its beautiful construction makes me burn film after film.
The Aqueducto das Águas Livres was built in the XVIII century by the king at that time to bring water from the countryside around Lisbon into the city. The main course of the aqueduct covered 18km so you can find parts of this beautiful construction in several locations of the city.
I think this is my favorite monument in Lisbon. I like both the construction and the purpose of it. Water distribution is a major issue in any society and often the constructions related to it are very beautiful.
The part of the aqueduct that crosses the Alcântara valley is the most impressive. It connects two hills and the cars pass through its magnificent arches. The place around this part of the aqueduct is not very pedestrian friendly, but I think it’s worth the risk!
It is possible to visit inside, it makes part of Lisbon Water Museum, Museu da Água, but I never did it – I got there after 6pm and I was more interested in shooting outside.
There are also other parts of the museum that are open to the public, mainly the reservoirs like the “Mãe d’Água das Amoreiras” and “Patriarcal do Príncipe Real”. You can learn more about it here.
