Historical sites in Munich (Birth and Rise of Nazism, and WWI Consequences)

I’m a huge WWII and Cold War history lover. A few weeks ago, I had the opportunity to visit the cities of Munich, Berchtesgaden, Obersalzberg, Landberg and Dachau to tour these cities and walk the steps where history was made. Sadly, all these places had a pretty dark history, nonetheless, they are extremely relevant for us to understand and remind us of all the madness and insanity the world went through in the 1920s, 1930s and 1940s.
Let us never forget these events, and prevent history from repeating itself!
