As latest discoveries seem to prove (investigations at the University of Innsbruck are still ongoing), people are believed to have lived in Weissenbach since the early stone ages. Also Roman skeletons were found in Weissenbach in 1948. The Romans used to have an important salt trading route from Hall in Tirol to the Lake Constance, which mainly was used until the train was built through the Arlberg in the early 20th century. Many parts of the road are still in good order but were not used for karts or horses for many decades. The fact that Weissenbach is located at the foot of the steep Gaicht pass road meant extra horses were needed for the karts which made Weissenbach a pulsating center over the centuries. However this source of income stopped rapidly when the train over the Arlberg ranges was built.
