Some time ago I travelled to Madrid, Spain to help lead a multi-day technical training course and I found myself with some extra time to explore after my lecturing duties were complete. A review of the surrounding area yielded my discovery of Segovia, about 56 miles to the northwest. Further research into transportation options yielded a bus route that would take me there and back over the course of a day and provide time to do some exploration of the city.

Segovia is a UNESCO World Heritage Site situated in Castile and León, Spain. Three notable historical landmarks are located there – an intact Roman Aqueduct, an iconic gothic cathedral and an Alcázar (a term meaning, in this case, a castle built upon pre-existing Roman fortifications).

These landmarks, embodying Roman engineering and medieval splendor, define the city’s historical identity.

The Roman Aqueduct: An Engineering Masterpiece

The granite arches of the Roman Aqueduct, or “El Puente,” preside above Segovia’s Plaza del Azoguejo and showcase ancient Roman engineering brilliance. This magnificent structure serves as a symbol of the city and is one of the most intact and best-preserved Roman structures in the world.

History and Construction

Built in the late 1st to early 2nd century AD, likely under emperors Domitian, Nerva, or Trajan, the aqueduct carried water from the Frío River, 10.5 miles away, to Roman Segovia. The aqueduct uses only gravity as the water delivery system with a mere 3-foot drop over its entire length! The iconic elevated section in Segovia’s center features 167 arches, reaching nearly 100 feet at its peak.

The aqueduct is constructed without mortar, using over 24,000 precisely cut granite blocks from the Guadarrama Mountains, interlocked for stability.

Here is a closer look at those precisely cut blocks.

Function and Legacy

The aqueduct supplied water to fountains, baths, and homes, functioning until the 20th century despite almost 2 millennia of earthquakes and weathering. A plaque at its base, placed by the International Society of Civil Engineers, serves as a tribute to the designers and builders of this amazing, enduring structure.

The Mirador del Acueducto and Gothic Cathedral

Climbing the steps next to the aqueduct takes one to the Mirador del Acueducto, an overlook that provides a sweeping perspective of the aqueduct as well as scenic views of Segovia.

These steps also take one to the medieval walls of the old city of Segovia. Remnants of Segovia’s Roman heritage. Structures like as this classic Roman arch supporting the aqueduct as it enters the old city are prominent here.

Inside the walls of the old city, you tread through narrow, labyrinthine passages that once accommodated pedestrians and oxcarts and which today provide thoroughfare for ourselves and our automobiles.

Some of these passages, though, will only accommodate foot traffic, or perhaps a bicycle or motor scooter.

Eventually these passages lead to the plaza beneath Segovia’s magnificent gothic cathedral.

The current cathedral was dedicated in 1768 and is situated on the site of an original cathedral which was destroyed in 1520 as a result of the Revolt of the Comuneros.

Surrounding the cathedral are even more labyrinthine canyon-like passages that provide inspiring perspectives on the cathedral, its architecture and its history. Note the gargoyles high on the catherdral walls.

Walking through these narrow passages sometimes provides a glimpse into quiet courtyards that provide residents with a respite from the busy goings-on just a few feet away.

The Alcázar of Segovia: An Iconic Medieval Castle

Situated high above the convergence of the Eresma and Clamores rivers, the Alcázar of Segovia resembles a fairy-tale castle. In fact, its ship-like silhouette and slate-spired turrets inspired Disney’s Cinderella Castle. This fortress is a cornerstone of Segovia’s medieval heritage.

The Alcázar was constructed in the 12th century on the site of a Roman fort. It evolved over the next few hundred years from a strategic Reconquista stronghold, into a royal palace, prison, and artillery academy. Isabella I was proclaimed Queen of Castile here in 1474.

Historical Role

The Alcázar was pivotal during Ferdinand and Isabella’s reign, whose marriage unified Spain. It was here at the Alcázar that Christopher Columbus proposed his voyage to the new world to Isabella – which she ultimately approved and funded. Today, its museum displays medieval armor and royal artifacts, narrating Segovia’s past.

Exploring the Alcázar

Within the Alcázar you can catch glimpses of the Roman heritage on which the Alcázar was constructed. Here is an excavation into the depths of the Alcázar and into the Roman fort upon which the Alcázar rests.

The climb to the Tower of John II takes one up a tight spiral staircase inside one of the parapets. Here is a view looking downward.

Note the strategic construction; a right-handed attacker ascending the staircase is constrained by the central pillar from fully swinging a weapon while the defender above can swing a weapon more powerfully.

Once on the top of Tower of John II one is treated to panoramic views of the Alcázar as well as the surrounding countryside.

Here is Señor Trail on the Tower.

Segovia’s Enduring Charm

Segovia is an ancient city containing a Gothic cathedral, medieval walls, and labyrinth of narrow streets that add depth and humanity to this place. The aqueduct and the Alcázar frame Segovia’s story, inviting and encouraging one to explore this city where ancient stones whisper tales of Roman skill and medieval majesty.

I wish I had been able to spend more time here.
