Innerdeutsche Grenze
During the period of the post-war division of Germany, Eckertal was the site where the Inner German border along the Ecker interrupted the Bundesstraße 6. Likewise, Eckertal became the terminus for trains from Bad Harzburg and the railway tracks were finally dismantled in the 1970s. A restaurant and an observation post overlooking the border installations were a popular destination for day-trippers.
