リュクサンブール宮殿
Between 1613 and 1624 a bridge-aqueduct over 1300 ft. long was constructed to convey water from the spring of Rungis, south of Arcueil, across the Bièvre river to the Luxembourg Palace in Paris. Between 1868 and 1872 another aqueduct, still longer, was superimposed above that of the 17th century, forming part of the system conveying water from the river Vanne to Paris.
