With a length of more than 550 kilometers, the Roman Limes (border, border wall) is the largest archaeological cultural monument in Europe. Over the course of more than 100 years, the Romans built 60 forts, around 900 watchtowers and numerous smaller military installations along the border wall. Around 260 AD, the Limes was abandoned after the Romans had lost many battles against Germanic tribes. At Idstein-Dasbach, the reconstruction of a Roman watchtower on the Limes was completed in 2002, as it might have looked around 150 AD. The stone tower near Dasbach is considered by experts to be the most authentic reconstruction of a Roman watchtower.
The tower is twelve meters high and has a floor area of 25 m². How it was set up around 150 AD can be roughly reconstructed. It is assumed that there was a storage room on the ground floor, which is not accessible from the outside (coolest place). The entrance to the tower was on the first floor and could only be reached by a ladder. A picture of the likely interior of the tower can be found here. Up to six guards were stationed in the watchtowers on the Limes. Also at the Limesturm near Dasbach there were probably members of the auxiliary troops (from Latin auxilium = help). These were auxiliary troops of the Roman legions, who were recruited from allied tribes and peoples.
