House Built Inside A Mountain, Alps, Switzerland

Series of lower mountain ranges run parallel to the main chain of the Alps, including the French Prealps.
The geologic subdivision is different and makes no difference between the Western and Eastern Alps: the Helveticum in the north, the Penninicum and Austroalpine system in the center and, south of the Periadriatic Seam, the Southern Alpine system and parts of the Dinarides. Geographically, the Jura Mountains do not belong to the Alps; geologically, however, they do.
