The entire expanse, including the water catchment area, measures 560 hectares (5.6 square kilometres). Regarded as one of the largest in Europe, the park forms Germany’s 38th World Heritage site. The UNESCO committee decided to inscribe the Bergpark’s Hercules Monument and water displays on the list of the world’s cultural and natural heritage in June 2013, acknowledging the property as a unique cultural landscape. The selection was made on the base of the Bergpark’s water features posing “an outstanding example of the art of monumental water engineering practised in the era of European Absolutism”.
