Waldberg Empelde

More than thirty years ago, work began on covering this waste dump with construction rubble and excavated soil. Since then, a large portion of the site has been planted with trees and shrubs, transforming the former salt mine into a forested mountain with diverse flora and fauna.As part of this large-scale reclamation program, a valley was created on the mountain and prepared to accommodate a wide variety of events. The Empelde Forest Hill – just outside Hanover – has become a charming place where music, theater, literature, landscape conservation, and environmental protection events take place in the open air.

If you have a chance to visit this private hill during a public event, you should definitely do so as you have a very good view from the top.
