Tannbach is a brook that is around six kilometers long in north-east Bavaria and southern Thuringia, Germany.
The source is located east of Gefell in the Saale-Orla-Kreis district, in Thuringia, Germany. Initially it flows south through Gebersreuth before reaching Mödlareuth. During the Cold War the little brook marked the border between West- and East Germany and divided the little village into two parts. After Mödlareuth it flows in south-westerly direction before it joins the also known as the Saale as right tributary.
Tannbach is a German television series that first aired in 2015. It is the story of the fictional village of Tannbach in Germany at the end of World War II until the year of 1952. For the people in the village the end of the war does not mean the end of hardship, soon the Cold War takes over and the village as well as the people become divided.
