The Erbeskopf lies in the southwest of the Hunsrück and the Idar Forest - forming part of both natural regions - near their boundary with the Schwarzwälder Hochwald, to which it belongs morphologically.
In late August 1939 the tower was closed to civilians, three more storeys were added, military signals equipment was installed and it acted as the communication centre for a radio relay link from Berlin to the Atlantic coast.
Three large radar towers and the Erwin Bunker with the wartime headquarters for Central Europe (AFCENT) supported NATO strategy as a multinational command post during the Cold War.
In the wake of the political easing of tension between NATO and the so-called Eastern Bloc states the significance of the listening equipment and electronic alarm systems on the Erbeskopf waned rapidly.
Half a century after the end of the Second World War, American troops withdrew and the radar site continued in operation by the Bundeswehr.
After the Emperor William Tower was blown up and widescale clearing took place, there were only a few remnants to give a poor impression of the original ancient trees.

It offers an interactive exhibition on the nature of the Hunsrück, a woodland play park, a senses educational path, a weather survey garden, an environmental laboratory and a conference centre with modern media technology.
