Some man involved in nominating this site for Germany came over to speak in my class during Winter Semester 2015-16 when I was still enrolled in the master's degree program "World Heritage Studies" in Germany and said that they had given up nominating this site as a transnational serial site with 4 other state parties and had decided to go alone at it; thus another nomination called "Hedeby and Danevirke, an archaeological border landscape."
I took a Flix bus from Hamburg, which dropped me off at some gas station in Schleswig about 3 km away from the outdoor museum area. But luckily within a few minutes I found an elderly woman who lives in Busdorf near the museum and who gave me a ride to the museum area.
I had seen this kind of reconstructed Viking houses in Lofoten Islands in Norway, Birka in Sweden and Trelleborg in Denmark.
So I guess it may be a good idea to distinguish itself by presenting this area with such a different view point as archaeological border landscape with the remains of the earthwork.
