Our guide Alex from yesterday’s tour highly recommended the German History Museum, so we decided to check it out.  The museum covers the history of Germany from about 100 BC to the 1990s.  We arrived at the museum around 12:30 and didn’t leave until almost 17:00.  Originally, we were planning to visit some other Berlin sites like the Topography of Terror or Checkpoint Charlie after the museum, but we were so tired from experiencing the entire history of Germany that we just headed back to the hotel room to pack up for tomorrow’s journey.
