The Döppersberg caves ( more precisely: Döppersberg caves I and II ) were two small caves in the Wuppertal city area.
Location and description
The caves were located in the rock of the Upper Honsel Strata , which date from the time of the Upper Middle Devonian. This layer is mainly formed by clay slate and greywacke , which can have a more or less high lime content. In addition, there are also deposits of pure limestone that arose from coral and stromatopore reefs. These local calcareous lenses are often very karstified and have formed caves.
This layer is therefore also the rock layer in which the Hardthöhlen can be found around 1.5 kilometers away , a cave system that is one of the largest in the Rhineland. The Döppersberg caves were located near the building of the former Reichsbahndirektion Elberfeld , south of the Wupper .
history
The Döppersberg traffic junction was completely redesigned from December 2010. The Federal Highway 7 has been locked to the summer of 2014 for three years, so that they can be placed m lower to a length of approximately 600th
When working on the excavation below the Federal Railway Directorate, limestone was cut on the southern slope . With the mediation of the environmental department of the city of Wuppertal, two members of the working group Kluterthöhle e. V. (AKKH) entered the construction site for research purposes on June 19, 2015. Previously, an unplanned consumption of liquid concrete was registered by the construction work . The liquid concrete should consolidate the anchors in the subsoil.
With the help of heavy equipment, the entrance was enlarged. The inspection showed that there was a small cave with lye forms and no stalactites. It was measured and recorded as Döppersberg Cave I in the cave cadastre . A second, lower-lying small cave was recorded as Döppersberg Cave II in the cave cadastre. It was discovered in the area of the newly laid sewer pipes. The clay found it was able to establish that it was in direct hydrological connection to the Wupper and that the Wupper was flooded when the water level was higher. The AKKH assumes that the two caves were originally - before the time of the investigation - longer and possibly connected to one another.
Except for the dwarf cave on the Kluse, which was destroyed in the 19th century , no cave was known in the urban area south of the Wupper, so one was surprised to find one here. According to the documentation in June 2015, the cave or the caves have since been destroyed by the ongoing overbuilding.
