Located in the central mountainous area of the western plateau of Switzerland, Bern is situated in a natural bend of the Ale River, a tributary of the Rhine River. The turbulent river flows around the old city of Bern on three sides, forming a peninsula. Berne is a quiet and peaceful pocket city. The old city is strangely quiet. The river at the foot of the city is quiet. The ancient houses with red tiles and white walls are in the embrace of nature both inside and outside the city. The old city of Bern is one of the world's cultural heritage sites.
