At the foot of a mining slag heap rising to over 80 metres in height lies the Carl Alexander Park, which developed on the former colliery of the same name. The site in the urban area of Aachen now sends out a strong signal for sustainable regional development in this area close to where Germany, Belgium and the Netherlands meet. Due to its unique potential in terms of both natural and cultural spaces, some parts of the site are protected conservation areas, since the lack of human access to the decommissioned slag heaps has led to the development of a fascinating range of flora and fauna. 

The highlights of the park include the floating boardwalk at treetop height and the steps that lead up to the tip of the slag heap. Surrounded by the fascinating pioneer forest, visitors are guided along a ridge path to the plateau, where they are rewarded after the strenuous climb with a magnificent panoramic view over the surrounding mining landscape and the wilderness of the slag heap.

Down in the valley, the LandschaftsAder offers an extensive site for events as well as park and play areas suitable for various different uses. The site represents a cultural connection between the slag heap and the Wurmtal and forms the new point of focus in the open space.

At the same time, the park represents an engine for the attractive development of brownfield sites. Hence, for example, new multigenerational housing is being developed, along with a campus. This already forms a base for spin-off companies from the universities in the greater Aachen region and the ambitious workplaces that go with them.
