Ages as the Fief des Arcs. The arches of the bridge are the origin of its name, as well as that of the village itself. The Château des Arcs, built from 1548, encloses the remains of the aqueduct bridge. The bridge was about 300 m long, 18 m high and had a single level of arches. The Medici aqueduct bridge is very close to that of the ancient aqueduct. The collection basin The remains were rediscovered in the 19th century. They were subsequently excavated at the beginning of the 20th century by the Commission du Vieux Paris (CVP). The rectangular collecting basin joined a series of channels from the sources of the south, in particular those of Chilly and Morangis. The basin was later covered by metres of rubble despite its historical interest. Gallery References Roman aqueducts in France Roman Paris
