On the museum grounds is the top a guard tower that was removed from the Plauen area after the fall of the GDR. It was erected here on the museum grounds a third of it's original height. I found this one interesting, because of all the museums I've been to, this is the only tower that I've ever seen open. The only way up is with the ladder. Out the window is a bird's eye view of the entire border strip, it's probably like the view a prison gurad has. And the other side is only a few feet away. For comparison, right behind the museum is a full size one, which isn't open.
When Mödlareuth, don't make the mistake of just visiting the museum. All over the town are signs with pictures of how the town used to look before and during the german separation. It's hard to believe today that the stream in the middle of town(I'd call it a ditch) was the border between east and west. On the west side of town is the site of the town mill which was levelled to give the guards clear line of sight along the border. The family fled to the west by jumping out the back window of their house! Past the mill site is a long section of fence that is the beginning of a 5km trail along the former border.
After crossing the bridge that used to be the end of the western world, up the hill is the other part of the museum. Inside, there is a small giftshop that sells postcards and shows a movie about the recent history of the town(get your passport stamped, see my general tip). The film is 20 minutes long and can be viewed in German, French, and English. The film is a must-see! It's an impressive work. What makes the film so dramatic is watching events that were just a few feet away from the theater. The film was great, but I still think 18 euro for a DVD is a bit steep.
Favorite thing: When the border was opened in 1989, the East German government built a small border crossing for the town of Mödlareuth. During it's short life, the border control stamped all passports that passed through. Today, the border house is gone, but the lady in the movie theater has the stamp. She will gladly stamp your passport for you, or anything you buy in the gift shop. For those of you that like to collect stamps in your passport, this is a rare stamp from history.
