This is where the border between Hesse, Thuringia and Grabfeld ran in the Middle Ages. A Hessian customs office was documented here as early as 1306, which also served as a convoy border into the Seulingswald.
A stone monument erected in 1987 reminds of the historical importance of the square as a medieval border between Hesse, Thuringia and Grabfeld. Since 1306, the Hessian customs post and convoy border in the Seulingswald have been located at this point.
