>>6156688you'd also like st stephens cathedral in the heart of the city, roughly 1000 years old. other things you'd like and now I can't be fucked to get images are: karlskirche, votivkirche, palmenhaus, burggarten, riesenrad, rathaus, and the belvedere.
type each one of those into google and add "vienna" and you'll find everything you're looking for.
