Seuil de Naurouze
The Seuil de Naurouze, or Col de Naurouze, is the highest point (190 m above sea level) of the Canal du Midi in southern France.
It is the watershed point identified by Pierre-Paul Riquet when he designed and built the canal.
The obelisk has a dedication: "To Pierre-Paul Riquet, Baron Bonrepos, author of the Two Seas Canal in Languedoc".
It is erected near the site of the former octagonal holding tank, called the Bassin de Naurouze created during the building of the Canal du Midi.
The flow of water from the Bassin de St. Ferréol joins the Canal at this point.
