The Upper Harz Water Management System is the most important historic structure of dams, reservoirs, ponds and ditches in the world and was declared a UNESCO World Heritage Site in August 2010.
Starting from the Middle Ages, it was the main power source for the mining in the Upper Harz for over 800 years. It provided hydropower, especially for the mining of ores and the operation of the pumps. Today, there are 107 lakes, 310km of water ditches and 30km of underground waterways preserved; while 65 ponds, 70km of ditches and 20km of underground waterways are still in operation.
Discover this unique world heritage landscape via the many hiking trails, or by visiting some of the mines and the Cistercian Monastery at Walkenried which represent a unity of culture and nature.
