Venice! Venezia! La Serenissima! Impossible city! Preposterous city! Founded by refugees running from Attila the Hun. It was just a collection of little wooden huts in the middle of a marsh, but became one of the most powerful cities in the world. Constantly being invaded, constantly flooding… constantly… just… beautiful! Oh, you gotta love Venice. (The Doctor, 5×06 Vampires of Venice)
