Aqueduct of Águas Livres – Water Museum

Commissioned by King João V in 1731, this was the first system to provide Lisbon with a consistent water supply. Its resilient 58-kilometre network survived the 1755 earthquake. The Alcântara valley is crossed by 35 monumental arches stretching over 941 metres, with the largest stone arch reaching 65 metres in height and 32 metres in width. Although it was removed from the city’s water supply system in 1967, this monumental structure remains one of the most remarkable works of hydraulic engineering and one of Lisbon’s most recognisable landmarks.
