Residenz

Located in the heart of Munich is the Residenz, which served as the main location for the Bavarian Government from 1508 to 1918.  This is a gorgeous complex to visit, as of course the Bavarian Royalty would have it no other way.  For 13 Euros a person, you can explore the entire grounds and see this beautiful building.  Out of all the things to do in Munich of historical significance, this is definitely a top choice that all visitors should come see.
