[2][3] The name comes from the Große Trogfurt, which in turn is derived from the Trog-/Tockweg, a road that crossed the River Bode, a tributary of the Saale, and which was mentioned for the first time in 919.
[2][3] The Trogfurt Bridge was built from rubble stone in the years 1739/40[3] spanning the Bode at a ford on the Königsstieg ("King's Mountain Road"), which ran from Italy to Scandinavia and was one of the oldest German military and trade routes.
The crown of the 18.2-metre-high dam wall (424.9 m above sea level (NHN)) now acts as the Bode crossing.
From the Trogfurth Bridge it is only a few hundred metres to the plateau of the Lange and the ruins of the castles of Königsburg, Trageburg and Susenburg.
[3] From there is a roughly 6 kilometre long circular walk around the reservoir, taking in the aforementioned plateau and castles.
