It overlooks Lake Thun, in the Bernese Oberland region, and forms the northern end of a ridge that stretches north from the Albristhorn and Mannliflue, separating the Simmental and Kandertal valleys.
Originally the mountains name was Yesen. «An Yesen» transformed to Niesen. Yesen is yellow gentian and still flowers on the Niesen to this day.  Because of its shape, the Niesen is often called the Swiss Pyramid. The Niesen may have influenced some modernist paintings by Paul Klee, in which an abstracted pyramidal form is seen.

- Rosenthal, Mark. “The Prototypical Triangle of Paul Klee.” The Art Bulletin, vol. 64, no. 2, [Taylor & Francis, Ltd., College Art Association], 1982, pp. 299–310, https://doi.org/10.2307/3050222. “The title Niesen makes explicit another identity of the triangle besides the Egyptian pyramid. "Niesen" is the name of a pyramidally shaped mountain in the Bernese Alps on Lake Thun, not far from Klee's childhood home near Bern. The area was a favorite of Klee's for hiking and vacationing; in 1915 he spent several days with his friend Louis Millet in the town of Gunten, which faces the Niesen from directly across the lake. Klee's study of the mountain from a dramatic vantage point recalls his affirmation, six years earlier, that Cézanne was "the teacher par excellence." As in Cézanne's Mont Ste.-Victoire paintings (Fig. 2), Klee, in Niesen, contrasts the strength of the mountain stretching to the skies with a patchy landscape below.”
