"Treasures of the World – Heritage of Humanity" (a German-language television series) honors special sites from all eras and continents in over 250 episodes with short film clips. Despite their diversity, they have one thing in common: they have been declared UNESCO World Heritage Sites. One of the episodes presents the Canal du Midi. This is a connection – desired for centuries, but also considered technically impossible – between the southern coast of France on the Mediterranean and the expanse of the Atlantic Ocean.

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.

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

"A 240.129 km long, 2.25 to 2.50 m deep waterway was declared a cultural monument as a "bridge" between the Mediterranean and the Atlantic with 328 structures such as bridges - such as the canal bridge over the Orb -, locks - such as the 7 lock cascades of Fonserrannes -, tunnels, aqueducts and 49 canals over streams and rivers." says the documentary from "Treasures of the World - Heritage of Humanity", a television series that brings world heritage sites closer to the culture-loving viewer (in German).
