We passed through this region very often. We visited Landsberg, the Ammersee and the famous medieval event in Kaltenberg.
In Dießen you can see a permanent exhibition that is dedicated to the famous German composer Carl Orff (1895-1982) who lived there for many years. I loved to see hos "Carmina Burana" and the "Bernauerin" on German TV.
