100 Years of Wyssen – Anniversary Celebration November 14, 2026

What began in 1926 as a bold idea from the son of a mountain farmer in the Bernese Oberland has become an international success story. In 2026, we will celebrate 100 years of Wyssen. To mark the anniversary, we’ll be opening the doors to our company grounds on November 14, 2026 so you can experience this pioneering spirit firsthand. From the dedication of our new Hall D to historical insights, a film premiere, and a kids’ corner, there’s something for everyone.
