The origin of the very modest house was built in 1760 by mountain farmers and artisans (the "Whale"). It served as an accommodation for agricultural seasonal staff for the summer months.

In the late twenties the Dutchman Pieter Marius Kerdel, grandfather of the current owner, bought the buildings and fields of "Prätschli". He started pasture and livestock farming on the “Kerdelgut“.

At the end of the thirties, the houses “Bergfrieden" and "Wilhelmina“ were contemporary modernized. From that point on they were inhabited all year long. Because of displeasure about his occupied home country, the old Kerdel renamed one house in honor to the exiled Dutch Queen “Wilhelmina”.

After the war, young Dutch athletes enjoyed the charm and comfort of the house after exhausting ski trainings. The houses on the “Prätschli” remained for decades as a center for skiing enthusiasts and young Dutchmen. It was also the venue for skiing competitions like the legendary “Flying Dutchman” (Therefore the nick name for “Wilhelmina”: The “Dutch House”).

In 1978, the family Jacke-Kerdel left their residence "Hollandhus" at the upper forest walk. The Chalet "Wilhelmina" was further used as only a holiday home. In that time it was rebuilt and modernized for this purpose.
