History
Historically, Weissenstein was used for alpine farming and timber supply.
In the late 18th century, it became popular for its scenic views, attracting visitors and inspiring panoramic artworks.
The Kurhaus Weissenstein spa hotel was built in 1826/27 and expanded later in the 19th century.
The area saw a decline in spa tourism due to competition from the Alps and World War I.
Transportation evolved from post coaches in the 19th century to a railway tunnel opened in 1908, followed by chairlift service from 1950 until 2009, replaced by a modern gondola lift in 2014.
The pass road, built in 1765 and upgraded in the mid-19th century, remains one of Switzerland's steepest.
