This sluice is situated between Basel and Mulhouse on the Rhone-Rhine Canal, at the junction between the latter and the Rhine Canal.
Le Corbusier was not involved in the work on the sluiceway proper. He designed only the two buildings; the first one, the tower structure, accommodates the lock-keeper’s station along with the mechanical installations; the second building is reserved for the customs and navigation offices. It also comprises, on basement level, the personnel rooms, the garage and the heating plant.
“This sluiceway permits boats from the Rhine to pass via the Rhone toward Marseilles. At this juncture, there is no longer any discussion of whether we have to do with architecture or with engineering. This is a “constructed work”. The administration people and the engineers asked me to participate in their undertaking.” Le Corbusier
