To the south of Idstein the fortification wall, the “Limes” - which ran between the Roman Empire and the free Germania, crosses hills and valleys from west to east. The reconstruction of one of the watchtowers, as they were to be found within viewing distance of each other on the Limes, was officially opened in 2002.
