The San Sebastian Aqueduct, locally known as the Arcos do Jardim, is one of the best places to visit in Coimbra for travelers interested in architecture and historic engineering. Stretching over a kilometer, this imposing structure once carried water to the upper city, blending Renaissance design with remnants of a far older Roman aqueduct. It is also a great place to visit on a walking tour of Coimbra, especially when paired with the nearby Botanical Garden and university district.

Built in 1570 under King Sebastião and attributed to the Italian engineer Filipe Terzi, the aqueduct combines functionality with elegant design. Its sequence of arches rises gracefully along the streets leading toward the Alta, ending in a monumental gateway filled with sculptural details.

History and Significance of the San Sebastian Aqueduct

The Aqueduto de São Sebastião stands on the alignment of a Roman aqueduct that once supplied water to ancient Aeminium, the Roman settlement that preceded Coimbra. When urban demand grew during the Renaissance, King Sebastião ordered the construction of a new aqueduct in 1570, using the ancient foundations and course as a guide.

Architect Filipe Terzi, one of the most influential engineers working in Portugal at the time, was responsible for the design. The result was a structure that harmonized classical motifs with contemporary needs, improving Coimbra’s water system while adding monumental beauty to the urban landscape.

Over the centuries, the aqueduct became a defining feature of the university quarter. Today, it remains one of the top attractions in Coimbra’s higher town, admired as much for its historical importance as its elegant geometry.

Things to See and Do in the San Sebastian Aqueduct

The most striking feature is the “arch of honor,” the first arch as you approach from the garden side. Unlike the rest of the aqueduct, this arch is richly decorated: topped with a cornice, adorned with the Portuguese royal coat of arms, and crowned with a canopy supported by Doric columns. Above this rises a dome with a lantern, creating an impressive ceremonial gateway effect.

On either side of the arch are niches containing statues of São Sebastião and São Roque, both protectors against plague-an appropriate dedication for a structure tied to public water supply. These sculptural elements set the arch apart from the simpler, functional line of arches that extend across the landscape.

Walking alongside the aqueduct offers excellent photo opportunities, especially where its arches frame the greenery of the Botanical Garden. The contrast between stone and foliage makes this one of Coimbra’s most atmospheric urban walks.
