The architecture is classic European, with ornate facades and tram tracks running down the center of the street. The signs, such as "Lapis lazuli" and "Lamian," use Latin script and suggest a German-speaking environment. The overall aesthetic, including the building styles and tram infrastructure, is highly characteristic of Vienna, Austria. I am very confident this is in Vienna.

Country: Austria, City: Vienna.
