L'aqueduc antique de Metz.

Sous l'Empire romain, cet aqueduc permettait d'acheminer l'eau depuis la source des bouillons de Gorze jusque Divodurum, capitale des Médiomatriques. Il a sans doute été construit au cours du IIème siècle. 

Long de 22 kilomètres, son tracé est essentiellement souterrain. Il franchit la Moselle grâce à ce pont-aqueduc dont la longueur avoisine 1,2 km. Il est encadré à chaque extrémité par un bassin monumental. Caractère unique dans le monde romain, ce pont possédait une double canalisation sans doute recouverte d'une toiture en tuile à deux pans.

Des fouilles récentes, en 2016, ont permis de mettre en évidence une autre singularité de cet aqueduc. Entre Novéant et Dornot, le conduit alterne des parties enterrées ou semi aériennes suivant la topographie de l'endroit. Pour le mettre à l'abri des glissements de terrain, les romains ont mis en place un système de mur-poids. Ce qui n'a pas empêché le conduit de se fracturer en plusieurs endroits et à des périodes inconnues. S'agit-il d'une des causes de son abandon ? 

Rendez-vous aux coordonnées indiquées. Vous êtes alors au pied des arches les plus hautes de cet ouvrage.
Asseyez-vous et admirez !

In Roman times, this aqueduct brought water from the “source des bouillons” (a gushing spring) in Gorze down to Divodurum, the capital city of the Mediomatrici. It was most likely built around the 2nd century AD.

The aqueduct is 22 km long and mostly runs below ground. This above-ground aqueduct bridge crosses the river Moselle and is about 1.2 km long. It is one of the major feats of engineering of Roman Gaul. There is a monumental pool at each end. This bridge was equipped with a unique double canal system likely to have been covered by a two-sided tile roof unparalleled in the Roman world.

In 2016, new excavations revealed another distinctive feature. Between the villages of Dornot and Novéant, the conduit follows an alternating pattern of underground and semi-underground routes depending on the topographical features of the terrain. In order to counter the effects of unstable ground, Roman engineers resorted to a retaining wall. This did not, however, stop the structure from breaking in various places at different, unknown, points in history. Could this be one of the reasons behind its abandonment?

You are currently standing at the foot of the bridge's highest arches.
Feel free to sit down and enjoy the view!
