From Niederbieber, the Roman-Germanic Limes once ran further over the ridge of the Wingertsberg into the Aubachtal valley and then up the Alteck, continuing through the Gladbach-Heimbach-Weiser forest down to Sayn, where it exited the present-day Neuwied city area. In the Neuwied city area, there were about 35 Limes towers, one of which was located on the summit of the Wingertsberg. Not far from its foundations, which are preserved in the ground and currently built over, a model of this tower was erected in 1969/71 as a historical monument.
