At this special lock system there is also a mill with a small shop that sells products from the mill and the region. It's worth taking a look inside! We bought a spread with olive paste.

The German-language television series "Treasures of the World - Heritage of Humanity" uses short film contributions to honor special sites from all eras and continents that have one thing in common: they have been declared World Heritage Sites by UNESCO. One of the episodes introduces the CANAL DU MIDI: "...the Romans already dreamed of a waterway between the Mediterranean and the Atlantic. Powerful people and doers from Charlemagne to Francis the First failed to realize this idea, even Leonardo da Vinci tinkered with it in vain. It was not built until the end of the 17th century. The Canal du Midi is a technical masterpiece by an individual, someone obsessed with the idea, by Pierre Paul Riquet. ..." => https://www.ardmediathek.de/video/schaetze-der-welt/gcanal-du-midi-frankreich-folge-224/swr/Y3JpZDovL3N3ci5kZS82OTg2NDg2

The German-language television series "Treasures of the World - Heritage of Humanity" honors special sites from all eras and continents in over 250 episodes with short film contributions, which, despite all their differences, have one thing in common: they have been declared World Heritage Sites by UNESCO. One of the episodes presents the CANAL DU MIDI. This is a connection - desired in the minds of many centuries, but also considered structurally impossible - between the southern coast of France on the Mediterranean and the vastness of the Atlantic Ocean. The episode mentioned is available in the ARD media library at the following link: => https://www.ardmediathek.de/video/schaetze-der-welt/gcanal-du-midi-frankreich-folge-224/swr/Y3JpZDovL3N3ci5kZS82OTg2NDg2
