10 Best Preserved Roman Aqueducts

Roman aqueducts are among the ancient world’s greatest engineering achievements, built to carry fresh water across miles of countryside using gravity alone.

Most were constructed between the third century BC and the fourth century AD, supplying cities with water for baths, fountains, and daily life.

More than ruins, these structures reflect Rome’s belief in permanence, order, and public good. Their surviving arches still shape landscapes across Europe and the Mediterranean, standing as quiet reminders of a civilization that understood how essential water, infrastructure, and foresight were to lasting power.

Hadrianic Aqueduct Of Caesarea, Israel

Built between 22 and 10 BC and later expanded, the Aqueduct of Caesarea once supplied water to ancient Caesarea, a major Roman port city. Uniquely, the aqueduct runs directly along the Mediterranean shoreline, blending engineering with coastal landscape.

The Aqueduct Of Segovia, Spain

Constructed in the first century AD, the Aqueduct of Segovia carried water nearly 11 miles into the city. Its towering granite arches remain largely intact and have earned UNESCO World Heritage status for exceptional preservation and scale.

Pont Du Gard, France

Built in the first century AD, the Pont du Gard once carried water to Nîmes. Remarkably preserved, it later served as a medieval toll bridge, helping ensure its survival as one of the finest Roman engineering works in Europe.

Aqueduct Park, Rome

Stretching across Rome’s countryside, the Aqueduct Park of Rome preserves the remains of seven ancient aqueducts. Built between 272 BC and the Renaissance, the park offers rare insight into Rome’s vast water system, far from the city’s busiest crowds.
