The colonization of the upper Rhône Valley led these populations to specialize, developing uses, customs, and techniques that allowed them to live stably at high altitudes, such as preserving fodder and using wood in construction, especially larch.

A good example of this specialization is the Stadal: the typical hayloft/granary raised off the ground by stone "fungi" to prevent rodent access. The Walser also brought with them culture, legends filled with the mysteries of nature, the cult of saints, codes of behavior, ancient customs, and language. This language, in fact, is a particular variant of the southern German dialect, called Upper Alemannic, and is very similar to Swiss German in its most archaic form. In some areas, the Walser language is still spoken today.

There are countless testimonies of this ancient culture in Valsesia, and those wishing to learn more are advised to visit Casa Daverio in Alagna and the Walser Museum in the nearby fraction of Pedemonte. The former is a small museum house of new conception, where the past meets the modern and where it is possible to immerse oneself in the millennia-old history of the Walser people. The latter is housed in a house from 1628 and is a testament to the originality of the culture of an ancient people proud of its language and traditions.
