A simple cache, located very near from the old "The Aqueduct [Lisboa] by MAntunes". This place is too important to not have a cache about it.
Its the ex libris of the city of Lisbon, considered as one of the most remarkable works in hydraulic engineer of all times and one of the rarest and most complex systems of water supply from the seventeenth century preserved until today. The order of construction came from King D. João V in 1732 and only was concluded
about 100 years later in 1834, although in its generality the Aqueduct was ready in the end of the eighteenth century.
The Águas Livres (Free Waters) destined to supply the new network fountains that was getting bigger, were conducted from the springs, located near Sintra to the Reservoir of Mãe d’Água of Amoreiras.The arcade of Alcântara Valley is remarkable, not only by its extension – a total of 941 meters – but also for the height of some of its 35 arches. This monument has the biggest ogive stone arch of the world, with 65, 29 m high and 28, 86 wide.
Although not functioning since the 60s, given its historical and greatness, the Water Museum is intent on promotingand projecting the Águas Livres Aqueduct not only through the walks across it and guided visitsbut also through other cultural events.
