You find this sator square on a facade in Golling an der Salzach. The sator square, aka rotas square, is a palindrome that one can read horizontally and vertically, forward and backwards. The oldest representation of a sator square was found in Pompeii. [German]
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.
On a train journey from Bischofshofen to Salzburg, I took this photo of Golling Castle (Burg Golling) through the train windows. The castle houses a museum of local history.
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 this area. [German]
