In August 2006, I went to the Silent Night Museum (Stille-Nacht-Museum) in Hallein. It primarily deals with Franz Xaver Gruber who is considered the composer of the famous Christmas carol Silent Night (Stille Nacht, Heilige Nacht).
Learning about a town’s history by searching for historical murals: While walking through Hallein I came across this mural telling about the transport of salt boxes along the Salzach River.
At the Museum of Celts (Keltenmuseum) I learned a lot about the history of the Celts especially in the region of the Austrian state of Salzburg. The exhibition also told me about the history of the salt mines in the region of Salzburg.
