Segovia Aqueduct Guide | History, Architecture, & Tips

How to access the Aqueduct of Segovia

The Aqueduct cuts through the heart of Segovia, starting at Plaza del Azoguejo and running toward the Alcázar. You don’t need a ticket—it’s completely free to explore at any time of day. Simply walk beneath its mighty arches or climb to nearby viewpoints for sweeping panoramas. Segovia day trips often include commentary here, sometimes paired with visits to the Alcázar and Cathedral.

Aqueduct of Segovia in a nutshell

One of Rome’s greatest engineering feats, the Aqueduct of Segovia stretches nearly 17 km. Built from 25,000 unmortared granite blocks, its 167 arches soar up to 28 meters high, creating a monumental gateway into the city. Water once traveled from the Fuenfría spring through underground conduits, passed the Casa de Agua for filtering, and finally entered the city, an ingenious hydraulic system whose remains can still be traced on hiking routes outside Segovia. Even after two millennia, its balance, symmetry, and sheer scale make it a must-see masterpiece of design and durability, recognized as a UNESCO World Heritage Site.

Architectural highlights of Segovia’s Aqueduct

Mortar-free masonry

The entire Aqueduct is built without cement or mortar, just 25,000 precisely cut granite blocks locked in balance.

Double-tiered arches

At Plaza del Azoguejo, two levels of arches soar upward, designed to handle the valley’s depth while maintaining a perfect gradient.

Ingenious gradient

The Aqueduct drops just 1% over its 15 km route, a testament to Roman mathematical precision and surveying.

Length and scale

Originally around 17 km long, only about 800 meters are visible today inside Segovia, but it was once one of the largest aqueducts in the Roman Empire.

History of Segovia Cathedral

Commissioned in the late 1st or early 2nd century AD, under Emperor Domitian or Trajan, the Aqueduct served Segovia for over 1,800 years, carrying life-giving water into the city. It was repaired in the 15th century under Queen Isabella I and remained functional until the 19th century. Local legends say the devil built it overnight in exchange for a soul, only to be thwarted at the last moment. Today, crowned by a niche of the Virgin of Fuencisla and celebrated in city festivals, the Aqueduct stands as Segovia’s proud emblem and a UNESCO World Heritage treasure since 1985.
