Aqueduto da Água de Prata
An 18-kilometre aqueduct built in the 16th century by the architect Francisco de Arruda — the same behind the Torre de Belém — to supply the city with water. Its most photogenic stretch runs along Rua do Cano, where the arches have been built directly into the fronts of the houses.

An aqueduct that moved into people's homes
The Aqueduto da Água de Prata isn't a monument you step into: it's a 16th-century feat of engineering that runs through Évora and, along its final stretch, literally became part of the neighbourhood. On Rua do Cano (its name comes from the conduit itself) the arches show up bricked in, occupied, lived in: people built their homes right into the structure, and today you'll see doors, windows and pots wedged between the arches. That mix of national monument and street where someone's hanging out laundry is what makes the detour worthwhile, more than the scale of the work itself. The history helps explain it: King John III commissioned the aqueduct in 1534 from Francisco de Arruda — the same architect behind the Belém Tower — and it was inaugurated on 28 March 1537, after just six years of construction. It carries water from the springs of Graça do Divor, on land belonging to the Convento de São Bento de Castris, some 18km to the city, and very likely follows the route of an earlier Roman aqueduct. On Rua Nova de Santiago, where it cuts through the old city wall, Arruda built a Renaissance Caixa de Água with a square plan and twelve Tuscan columns: it's the detail most people skip and the one that best shows the ambition of the project. It's been a National Monument since 1910.
Tickets, hours, and why you won't find queues here
Good news for the budget: access is free, no charge. There's no ticket booth, no enclosed site and no online booking, because this isn't a building you visit but an open-air urban feature you walk along the street. For the same reason, there's no opening or closing time: you can see it any hour of the day. What can cost money are guided tours run by third parties that include it as part of an Évora itinerary; if that interests you, check prices directly with the operator. Queues, in the classic sense, you won't find. What you will find are busier moments with worse light: the Rua do Cano stretch is narrow and fills up with groups coming down from the centre around midday. Before heading out, it's worth a quick check on cm-evora.pt, since there can occasionally be works or closures on a section that aren't always announced in advance.
Getting there and tips to handle the Alentejo
Évora is small and entirely walkable: from Praça do Giraldo you'll reach the urban stretch of the aqueduct in a few minutes on foot. There's no metro. Urban buses exist (the Rodoviária do Alentejo / TransDev network), useful mainly if you're arriving from the train or bus station, but within the historic centre a car or bus gets in the way more than it helps. With 20-30 minutes you can cover Rua do Cano and its surroundings comfortably within a stroll through the centre. If you want the full plan, there's a hiking route of around 8.5km that follows the aqueduct outside the city walls, starting on the road towards Arraiolos with three access points; maps are available at the tourist office, where it's also worth asking about the current state of the path. Set aside half a day for that. The tip you'll appreciate most: go early in the morning or late in the afternoon. The low, raking light is what makes the arches read well in photos, and above all you'll avoid the heat — in August Évora easily tops 35°C and that stretch has little shade. Bring water and comfortable shoes: the cobblestones of the historic centre are unforgiving.

Other places in Évora
Templo de Diana
temploThe best-preserved Roman temple on the Iberian Peninsula, dating from the 1st century and dedicated to the imperial cult (most likely Augustus, despite the popular name). It survived because it was absorbed into a castle during the Middle Ages. Its 14 Corinthian columns, right in the historic centre, are Évora's most photographed sight.
Sé de Évora (Catedral)
catedralPortugal's largest medieval cathedral, built between 1280 and 1340, blending Gothic with late Romanesque and featuring two asymmetrical towers. Entry to the cathedral alone costs 2 €; adding the cloister, panoramic terrace and museum brings it up to 4.50 €. You can climb the bell tower via a 135-step spiral staircase to a terrace with views over the whole Alentejo.
Capela dos Ossos
capillaAttached to the Igreja Real de São Francisco, its walls and columns are covered with the bones and skulls of around 5,000 people, the work of 17th-century Franciscan monks. Above the door, an inscription warns: 'Nós ossos que aqui estamos, pelos vossos esperamos' ('We bones here await yours'). The ticket (6–7 €, free under 12) includes the museum core, the nativity-scene (presépios) gallery and the panoramic terrace.
Praça do Giraldo
plazaÉvora's living room since the 16th century, anchored at one end by the Igreja de Santo Antão and its eight-spout marble fountain. Ringed by arcades, cafés and shops, it once hosted Inquisition autos-da-fé and is now the starting point for any walk through the historic centre.
Universidade de Évora (Colégio do Espírito Santo)
universidadFounded in 1559 by the Jesuits, it's Portugal's second-oldest university after Coimbra. Its two-storey Renaissance cloister and 18th-century azulejo-lined classrooms, including the famous 'Sala dos Actos', can be visited while it continues to function as an active university; entry (3 €) is usually free outside the 25 July–31 August period.
Feira de São João de Évora
fiestaÉvora's biggest fair has run since 1569, when it was the livestock market that set prices across the Alentejo. Today it's roughly two weeks of tasquinhas (food stalls) and free concerts on the Rossio de São Brás, just outside the walls. Entry is free to the whole site, shows included.
Festival Imaterial
fiestaImaterial is Évora's intangible heritage and world music festival, run by the Município together with the Fundação Inatel under the motto "Pensar e Viver o Património" (Thinking and Living Heritage).
