The Justizpalast or "Palace of Justice" is one of the first sites you see walking from the train station to the old town Karlstor Gates at the Karlsplatz. It's worth stopping and admiring this beautiful Neo-baroque 19th Century building, as it is one of the few surviving examples of this architecture in Munich to survive the bombings of World War II. It's an administrative courthouse building, but you can enter for free and quietly walk around to see the interior unless something unusual is happening. The interior is lit up by a huge central glass dome, and you can see Room 253, where members of the Nazi opposing "White Rose" movement were put on trial in 1943. Good stop for history and architecture lovers.
