Aqueduto das Águas Livres
Opened in 1748 to supply water from the Águas Livres in Caneças to the Casa da Agua in Amoreiras, a distance of more than 18 kilometres.Constructed by the architects Manuel da Maia and Custodio José Vieira, it is one of the most baroque monuments the capital possesses.
Although partly subterranean,
the visible stretch obliged the engineers to erect 109 stone arches.
Due to the type of soil in
Alcántara valley,they were forced to build 14 cone-shaped
arches. For more than twocenturies, these arches have never failed to impress
those who look at them. The aquaduct can be seen in all its dimension from
several points of the city.
