Water

It's the ex libris of the city of Lisbon, considered as one of the most remarkableworks 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 was concluded
about 100 years later in 1834, although in its generality the Aqueduct was ready in the end of the eighteenth century.
