Two days ago Google uploaded this video showing Stuttgart and Berlin, the capital cities of Baden-Würtenberg and Berlin/Germany respectively, in 3D. There you can see some of my models, like the Staatsoper, St. Hedwig's, the Kanzleramt, Zeughaus, Gendarmenmarkt (excepting the French Cathedral), Soviet War Memorial in Tiergarten, etc. Along wih them, there are more very good models like the Reichstag, "Kommode" and Branderburger Tor by Emperor Heer, Kongresshale by Michael Riese, and JWagner's Tempelhof Airport.

Also, and although I personally dislike BM models, I must say that I have seen excellent online-modeled buildings. Some examples are the Hotel am Hauptbahnhof, the North Korean Embassy on Kaiserhofstrasse, Schinkel's Bauakademie and the Bahnhof am Alexanderplatz.
