The distinctive hill landscape between Raron and St. German has a prehistoric past, due to its location above the valley of the river “Rotten”. Various objects from the Neolithic and the Bronze Age, have been found in the 60s, among them the oldest plough marks from Switzerland.
The name Heidnischbiel signifies “locality of the gentiles” understood as non-Christians.The landscape is a unique jewel of the Valais dry steppe, and therefore listed in the Federal Inventory of Landscapes and Natural Monuments (BLN). Rare plants and animals such as orchids, feather grass, houseleek species or the green lizard can be found here. Towards the west, Heidnischbiel ends with the castle of Raron and its castle church St. Romanus.
