Two main things to see in Munich are, of course, Marienplatz and Frauenkirche. On most postcards you find either Dom or Townhalls ('old' and 'new'), the only exception I can admit is Octoberfest, but it is a season thing, and mostly a cultural event, not the city sightseeing. This is a photo of Marienplatz. Marienplatz is a magneto - all tourist roads lead to this square.
