Grosses Fiescherhorn is a mountain peak of the Bernese Alps, located on the border between the cantons of Bern and Valais, halfway between the Mönch and the Finsteraarhorn.

The summit was first reached on 23 July 1862 by H. B. George and Adolphus Warburton Moore, with guides Christian Almer and Ulrich Kaufmann.

On 13 August, W. Amstutz and P. von Schumacher reached the summit after a 15-hour ascent via the north ridge, which is the northern boundary of the Fiescherwand.

Welzenbach was an expert climber, who disputed the common idea of his time that an ascent of the Fiescherwand was impossible.

[3] The following year they started the ascent of the Fiescherwand on the morning of 5 September 1930, taking a line that ran directly to the summit.
