Setúbal Aqueduct, Aqueduct in Setúbal, Portugal

The Setúbal Aqueduct, also known as Aqueduto dos Arcos, is a stone structure with two tiers of arches in Setúbal, Portugal. It features wide lower arches and narrower upper ones, and parts of it cross roads where vehicles pass beneath.

Built in the late 15th century under King John II, the aqueduct once carried water from Alferrara to the city walls. Over time, urban growth left only a few sections, and it was classified as a Property of Public Interest in 1971.

The aqueduct is a symbol of Setúbal's past, and its arches are a familiar sight in the cityscape. Local residents often refer to it as Aqueduto dos Arcos, and it remains a point of reference in the neighborhood.

You can see the aqueduct by walking along Estrada dos Arcos, where sections stand near the road. It is best viewed on foot, and you should be careful of traffic when crossing under the arches.

The aqueduct once had branches that supplied the eastern part of Praça do Sapal, a detail often missed. Also, the Chafariz do Sapal was built in 1693 in front of the town hall, connected to the same water system.
