The Lisbon Aqueduct is a fourteen km (12mi) long reservoir conduit that was inherent the eighteenth century to supply crisp water to the city of Lisbon. The water passage compasses the Alcântara valley with a progression of thirty-five long curves. It has recorded until today the biggest stone ogival arch in the world, reaching 65 metres high and 29 metres wide.
In the mid eighteenth century, clean drinking water was hard to come by in the quickly growing city of Lisbon.
Because of this issue, ruler John V chose to assemble a water passage that would bring water from the Mãe d’água well in the slopes around the city to a store in Amoreiras, close downtown Lisbon. The task was financed with duties collected on sustenance items, for example, meat and olives.
Development on the fourteen kilometer long reservoir conduit began in 1731. Outlined by specialist Manuel da Maia, the reservoir conduit was one of the biggest building undertakings of now is the right time, and the great 941 meter long extension that compasses the valley of Alcântara was a wonder of designing. The focal curve, 29 meters wide and about 65 meters (213 ft) over the ground, was at the time the biggest curve on the planet.
The fundamental compass over the valley was constructed by José Custódio Vieira and finished in 1744. It would last until the nineteenth century before the entire system of water lines with a few branches – fifty-eight km altogether – would be finished, however as of now in 1748, only four years after the consummation of the principle compass, water began coursing through the reservoir conduit.
The water system would soon end up being firmly developed; when the seismic tremor of 1755 with an extent of up to 9 on the Richter scale harmed the majority of Lisbon’s structures, the reservoir conduit survived unscathed. It would keep on furnishing Lisbon with water until 1973.
Today the water system is overseen by the Museu da Água, which every so often sorts out voyages through the reservoir conduit. On the off chance that you need to appreciate the great curves of the reservoir conduit over the Alcântera valley, you can stroll to the Calçada da Quintinha road or go the Campolide train station where you have a practically unhindered perspective of the fundamental compass separately from the south and the north part.
