Since Linz has a long history and for this reason has an old town worth seeing, a visit to Altstadt is clearly on the agenda. The ACT team wandered through the small alleys and listened attentively to the explanations of the city guide, who was able to explain the history of the city in bright pictures. Although it was icy cold, we stood for a long time in front of the old buildings and closely examined the facades of the buildings. The tour ended at Linz Cathedral, where we looked closely at the colorful stained-glass windows and also learned about the history of Austria.
