Roman aqueduct
Rome's first aqueduct was built in 312 BC, and supplied a water fountain at the city's cattle market. By the 3rd century AD, the city had eleven aqueducts, sustaining a population of over a million in a water-extravagant economy; most of the water supplied the city's many public baths. Cities and towns throughout the Roman Empire emulated this model, and funded aqueducts as objects of public interest and civic pride, "an expensive yet necessary luxury to which all could, and did, aspire".

In the early 18th century, King John V, ordered the construction of an aqueduct to transport water from the parish of Caneças to the city of Lisbon, which suffered from chronic lack of water. The Águas Livres Aqueduct, which began to operate in 1748, is one of the masterpieces of ancient Portuguese engineering.
