You only see what you know (Goethe)
The lindworm fountain (Lindwurmbrunnen) is the landmark of Klagenfurt am Wörthersee. In addition, the lindworm is also part of the local city arms. The sculpture dates back to the 16th century and refers to the foundation legend of the city. [German]
The house sign of the Pilatushaus in Nuremberg shows Saint George fighting the dragon. The motif fits well. The owner of this home was a Plattner (amorer), and George was the Saint of his craft guild.
This dragon was one of four I saw at the Dragon Bridge (Zmajski most) in Ljubljana. The bridge finished at the beginning of the 20th century shows some elements of the Viennese Secession. The dragons saw their production in Vienna (Factory A. M. Beschorner).
To my surprise, one of the frescoes at the church of Altenburg Abbey (Stift Altenburg) includes a dragon. The creator of these frescoes was Paul Troger.
