2 Best Sights in Évora and the Alentejo, Portugal

This impressive structure from the 11th century used to ferry water to Serpa from wells in the countryside. In the 17th century, a wheel pump was added just outside the city's southern walls, and still stands there today. Follow the aqueduct's walls from the pump out across the city's west side.

The 8-km (5-mile) Amoreira Aqueduct took more than a century to build and is still in use today. It was started in 1498 under the direction of one of the era's great architects, Francisco de Arruda—who also designed the Aqueduto da Água da Prata north of Évora. The first drops of water didn't flow into the town fountain until 1622. Some parts of the impressive structure have five stories of arches; the total number of arches is 843. The aqueduct is best viewed from outside the city walls, on the road from Lisbon.
