Stained glass window painted in grisaille, enamels and silver yellow on smooth glass in the Renaissance spirit.

It represents two men-at-arms, a halberdier and a standard-bearer, in the background a mountain. In the upper left part, a village attack. In the lower part in the center, a coat of arms with two keys. This coat of arms with two keys is that of the Swiss canton of Nidwalden (a double silver key on the background of the mouth). On the stained glass we also find, the mention “unter walden” (under the woods), this term is used to evoke the union of two regions Obwalden and Nidwalden at the end of the Middle Ages.
