I visited the Wien Museum at Karlsplatz a week or so ago when I was visiting Vienna with a friend. It's a huge museum, but the reason we were there is for the exhibit, "Vienna. My History." It's the museum's permanent exhibit, and it's free to visit. (When you walk into the the museum, just walk straight, and you end up entering the exhibit. You don't have to pay for admission if you're just visiting for that exhibit. And - wow. What an exhibit. I'm so glad we visited on what was my first visit to Vienna, because the exhibit is incredibly comprehensive. It includes over 1,700 objects, from prehistoric to contemporary times. It spans three levels of the museum and 35,000 square feet. I learned so much about Viennese and Austrian history from the exhibit - it's a great exhibit to visit early on in a visit to Vienna, because it will give context to so much of what you'll see as you walk and explore the city. I highly recommend visiting for this incredible exhibit - what a wonderful thing to make free for visitors! read more
