The aqueduct was engineered to move water over a distance of nearly 14 kilometers, though the prominent arcaded section is significantly shorter.
The two-tiered design was specifically chosen to maintain a precise, subtle slope required for gravity-fed water flow.
Engineer Henri Pitot is also known for the Pitot tube, a device still used globally to measure fluid flow velocity.
The structure historically supplied the city's fountains and private residences, ending the practice of hauling water from distant wells.
The arches cross the valley that once served as the natural boundary of the medieval city.
It remains an iconic example of 18th-century hydraulic civil engineering in the Languedoc region.
The Aqueduc Saint-Clément, also known as the Arceaux Aqueduct, is an 18th-century structure in Montpellier designed by Henri Pitot to transport water from the Saint-Clément spring to the city center. It stretches 880 meters and is characterized by its distinct two-tiered row of arches, modeled after the Roman Pont du Gard. The construction was completed in 1765 after nearly a century of planning and labor to resolve Montpellier's severe water shortages. It terminates at the Château d'Eau, a hexagonal reservoir located at the Place du Peyrou. The structure spans the Promenade du Peyrou and creates a visual gateway to the historic district. The arches are built from local limestone sourced from nearby quarries.

Walk the full length of the Promenade du Peyrou to observe the water's destination at the Château d'Eau.
Visit the market held directly beneath the arches on Tuesday and Saturday mornings for a local experience.
The area is best navigated on foot as the arches connect several major pedestrianized districts.
Do not attempt to climb the structure, as the stonework is fragile and the areas are monitored for safety.
