The aqueduct is slender, and held together without mortar, but even so it has stood since around 200 AD. That's more than 800 years!
The famous arches run along the nearby streets, before opening out across the valley. Point and click to follow the line of the aqueduct, then turn right to see it grow to its full height.
The tallest arches tower over the Plaza Artillería at 29 meters high.
The aqueduct is considered by many to be Spain's finest example of Roman architecture. Use the arrows to explore the aqueduct and the city's other treasures.
