What I didn't realize till today was that it was here at Odeonsplatz that Hitler's fumbled "putsch" came to an end in 1923. And I also didn't realize that an area I regularly cross on my way to Starbucks was a cafe Hilter used to frequent before he came to power.
The garden with the palisades is the Hofgarten, which has a monument to the White Rose movement, a group of students (and a philosophy professor) from the University of Munich who distributed leaflets against Hitler from 1942-43.
All three of these were beheaded by guillotine after they were caught (Hans and Sophie Scholl, Christoph Probst), along with others. A stupid janitor turned them in. Let his name stand here in disgrace: Jakob Schmidt. Sophie flung a last bit of leaflets into the air in the atrium of the university, again, a place I walked through even today. Janitor probably didn't like her making a mess... turned them into the Gestapo.
