Aqueduct in Coimbra

San Sebastian Aqueduct, known locally as Arcos do Jardim, is an outdoor landmark in Coimbra, Portugal, set beside the Botanical Garden of the University of Coimbra and along the city streets leading uphill toward the historic upper town. It is a Renaissance aqueduct built to carry water to the city's higher areas, and today it reads as both infrastructure and street monument.

Visitors see a long run of stone arches, a ceremonial arch with sculptural decoration, and the strong contrast between masonry and the garden greenery beside it. The aqueduct is best for people interested in architecture, urban history, and short walking stops rather than long sightseeing sessions. It works well as part of a visit to Coimbra’s university area, and it is easy to appreciate even if you only spend a few minutes here.

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.

Aqueduto de São Sebastião / Arcos do Jardim sits on Alameda Júlio Henriques beside the University of Coimbra Botanical Garden and stretches roughly a kilometre with a series of arches; visitors note its impressive, well-preserved ancient construction and statues marking its ends, and recommend viewing it from the street on the way to the garden or peering through openings in the garden wall when the grounds are closed.

"Built between 1568 and 1570 by order of King Sebastião (D. Sebastião) and designed by Filipe Terzi, this aqueduct was constructed on the remains of aformer Roman structure. Its purpose was to supply water to the Alta (Upper Town) of Coimbra. The aqueduct is approximately 1 kilometer long and composed of 21 arches. A statue of Saint Roch (São Roque) stands at the northern end, while a statue of Saint Sebastian (São Sebastião) marks the southern end. Due to its location beside the University of Coimbra Botanical Garden (Jardim Botânico), it is also commonly known as Arches of the Garden (Arcos do Jardim)...."

"While at the University I realized we were by the aqueduct so we walked by to glance at it. Dating from 1570 it is impressive, but not as impressiveas the Roman aqueduct in Segovia, Spain. It’s a short stop to take a few photos, then move in...."
