What Roman aqueduct in Spain, built without mortar, still stands in Segovia?

The Roman aqueduct in Spain built without mortar that still stands in Segovia is the Aqueduct of Segovia.

The monument carried spring water from the mountains to Segovia, supplying fountains, public baths, and private homes. Its construction is generally placed in the first or early second century AD, although the exact date remains debated. Earlier scholarship connected it with Domitian and proposed AD 98, while later archaeological evidence points to construction after AD 112, under Trajan or the early Hadrianic period.

The elevated bridge is made from carefully fitted granite blocks without mortar. Its tallest point reaches about 28.5 metres, including the foundations, and the surviving route contains 167 arches. Water travelled through a channel at the top, after passing through settling tanks and along a gently descending course from the mountains.

The aqueduct remained in service until 1973 and is one of Segovia’s defining symbols. A section damaged in 1072 was rebuilt in the fifteenth century, but the restoration followed the original style closely. It is often confused with the Pont du Gard in France, another famous Roman aqueduct bridge, but that structure is not in Spain.
