Nollen, Hill in Wuppenau, Thurgau, Switzerland

Nollen is a 735-metre hill in the municipality of Wuppenau, Thurgau, on a plateau between the Thurgau and St. Gallen sections of the Thur valley. Its rounded, tuber-shaped profile gives it the nickname "Rigi of Thurgau". A hotel with restaurant stands on the summit, and the view takes in Lake Constance, the Alps and the Hegau.

The name comes from Old High German words 'hnol' or 'chnol', referring to the mountain's bulbous or tuber-like shape. In the 1800s, it served as a triangulation point for surveying and mapping the surrounding landscape.
