Creating the two corresponding granite sculptures involved the use of 250 m³ of pale, fine-grained Tittlinger granite of similar structure, texture and flawlessness to build a 288 m long structure that rises up to 14 m in height. The natural cleavage plane of the front stones, which measure up to 13 m³, presented a major challenge. Their dimensional accuracy is + -1 mm.

"The granite sculpture marks the line of the European watershed shown on the location plan on both sided of the canal. At the highest point of the terrain the sculpture arises from the ground and, taking into account the typographical situation, rises slowly to the banks of the canal and breaks off at the edges of the embankment. Visible from afar from the water side, the light granite rises like a sail from the green embankment of the canal. As one approaches the sculpture and travels past, it tapers in perspective to a narrow triangular mark rising above the upper embankment. This impression creates the idea that the highest point of the journey, at the watershed, has been reached."
