The ancient Romans had a military camp in Dorlar, and in Waldgirmes directly on the eastern outskirts of Wetzlar was a civil settlement under construction. Presumably, the provincial government for the occupied territories of the right bank of Germania was planned at this location. The governor of Germania, at least temporarily, likely had resided here. The settlement appears to have been abandoned by the Romans after the devastating Battle of the Teutoburg Forest failed in the year AD 9. The Chatti were also involved in the Revolt of the Batavi in AD 69.
