Aqueduc de Castries Travel Guide

The Aqueduc de Castries is the largest hydraulic structure ever created in France for a private individual. Conceived by René-Gaspard de la Croix de Castries, who enlisted the expertise of Pierre-Paul Riquet, the engineer behind the Canal du Midi, the aqueduct was designed to bring water to the Château de Castries' park, as commissioned by the renowned landscape architect André Le Nôtre. Constructed from local Castries stone, the aqueduct spans 6,822 meters with a subtle slope of only 3 meters.The most visually striking section, known as the Grand Arches, rises approximately twenty meters in height and is located near the town's historic center. The aqueduct's construction, which took six years (1670-1676), faced numerous challenges, including the collapse of arches and local resentment due to water scarcity. Today, visitors can explore the aqueduct via hiking trails that wind through vineyards and pine forests, offering a blend of nature and cultural heritage. The surrounding area provides scenic walks suitable for families, with marked trails that lead to the medieval center of Castries, its castle, and park.
