Your title reminded me of the song by the late master, Leonard Cohen, whose lyrics were incredibly emotionally evocative.

I'm really getting a vicarious enjoyment from you trip. I visited most of these cities, but literally decades ago, so the recollections are a bit sketchy (also didn't visit all of the sites you've mentioned).

Vienna, is one of the repositories/well-springs of Western culture, on par with Paris and Rome, even if not usually thought of in the same category.
