The „Heidenturm“ is part of the 420-meter-high rock ridge "Heidenberg" (near Busenberg/Erlenbach) in the southeastern Wasgau, which rises directly south of the Drachenfels castle ruins. On the western slope of the ridge is the striking rock formation „Buchkammerfels“, and at the easternmost corner of the mountain lies the „Schlüsselfelsen“, also known as „Heidenpfeiler“. Due to the name "Heiden“, a Celtic settlement can be inferred.
