Kelheim to Canal Summit

The section between the summit of the Main-Danube Canal and Kelheim has a controversial history. So controversial, in fact, that construction was halted for 10 years.

Proponents of the canal argued that it would bring economic benefits by linking the Rhine, Main and Danube rivers to create a navigable route between the North Sea and the Black Sea, boosting trade and tourism. Supporters emphasised the jobs created during construction and the long-term economic opportunities for towns and cities along the canal, including new infrastructure and increased visibility for the region.

Initially, the project faced fierce opposition from local communities, environmentalists and conservation groups who objected to the disruption of the valley's natural and cultural environment. Several campaigns were launched to stop or modify the project, with demonstrations and petitions highlighting the value of preserving the Altmühl Valley.

The Altmühltal Nature Park, Germany's oldest and one of its largest nature reserves, covering over 3,000 square kilometres (74,000 acres), is renowned for its stunning limestone cliffs, meandering rivers and unique ecosystems.

The canal required significant water diversion and regulation, raising concerns about the long-term effects on local groundwater levels and natural hydrology, with many arguing that the natural meanders and ecological integrity of the valley had been destroyed.

To address some of these concerns, compromises were made in the design of sections of the canal through the Altmühl valley:

- Certain areas retained a naturalistic appearance, incorporating elements such as widened channels and landscaped embankments to blend in with the surroundings.

- Conservation measures were introduced to protect endangered species and restore affected areas.

While the Main-Danube Canal has since (25 September 1992) become a vital waterway and a boost to river tourism, the debate surrounding its construction remains a poignant example of the tension between industrial development and environmental protection.

At Kelheim, the majestic Liberation Hall overlooks the old town and the confluence of the Altmühl and Danube rivers.

Enjoy this absolutely fascinating stretch on your journey and judge for yourself whether it was a costly white elephant and human folly or a brilliant piece of German engineering. Look out for medieval towns such as Berching, the mighty Plankstetten Abbey and the magnificent castles of Eggersberg, Prunn and Randeck.
