This year was the 15th anniversary of Lange Nacht in Austria. For 13 EUR from 6pm - 1am everyone…read morehad access to museums all over Austria. My husband and I decided to stay in the third district and hit the Belvedere, Bahnorama, and Aresenal (Heeresgeschichte Museum). All lie on the 18 Strassenbahn. We didn't take the L2 Bus that was provided by the city in order to expedite our commutes. Our first stop at Oberes Belvedere had a major line beginning at 6pm. We decided it was best to only see the oberes even though there are two more parts, unteres and winter palais. The second stop was the soon to be destroyed Bahnorahma. It is a tower that was built to get an overview of the construction of the new Hauptbahnhof. This stop slowed us up majorly. We waited 45 mins in line for an elevator ride up to the top, and were only allowed 5 mins when arricing up there. A little lame, but totally worth the wait. There is no other view of the city from this side of town. I got photos that I can never get again:) After a pit stop at the Cafe Bahnorama, we hopped on the 18 back to the Military Arsenal Museum. No line there! This place is so huge and daunting it is unbelievable! The frescos alone are worth the trip. On this night there was a special presentation of WWI uniforms. Quite interesting to learn as a foreigner who is far removed from the WWI fallouts. The museum is divided into sections before WWI, during, and after. You can get up close to the car Ferdinand was shot in, bunkers, airplanes, tanks, canons, guns, etc. The whole concept of the museum though is to preserve history and runs under the slogan " War belongs in Museums". Pretty cool concept. To top off our long evening, the arsenal served up free chili and bread. YUM!! And thank you. Next year I think I will finish up my 3rd district tour with more Belveder and the 21. haus. Three in one night were enough for us!
