This 360-km network of navigable waterways linking the Mediterranean and the Atlantic through 328 structures (locks, aqueducts, bridges, tunnels, etc.) is one of the most remarkable feats of civil engineering in modern times. Built between 1667 and 1694, it paved the way for the Industrial Revolution.

The Committee decided to inscribe the nominated property on the basis of cultural criteria (i), (ii), (iv) and (vi) considering that the site is of outstanding universal value being one of the greatest engineering achievements of the Modern Age, providing the model for the flowering of technology that led directly to the Industrial Revolution and the modern technological age. Additionally, it combines with its technological innovation a concern for high aesthetic architectural and landscape design that has few parallels. The Committee endorsed the inscription of this property as the clearly is an exceptional example of a designed landscape
