The time windows on this route tell of gigantic changes: from Celtic times to the 20th century, mining and open-cast mining shaped the area around the town of Eschweiler. The mining of lignite brought work and prosperity, but villages and landscapes disappeared to free them up. Now man and nature are bringing about new change: the abandoned mining areas have been transformed into extensive recreational areas. Today, water covers old mining areas and children play where the mines used to be. But what has passed should not be forgotten, so look through the time windows along the trail and immerse yourself in the images and sounds of places that have long since disappeared.

Highlights along the route:

• Blaustein-See time window
• Lürken time window
• Langendorf time window
