Troldborg Ring

The Troldborg Ring is a significant Iron Age fortification located in Vejle Municipality, Denmark. This archaeological site, constructed between 100 and 200 CE, features a circular rampart and a moat, strategically positioned on a high point overlooking the Vejle River Valley. It served as a refuge during periods of violence, rather than a permanent dwelling, and was in use until around 400 CE. The site's location, near the later Ravning Bridge, suggests its strategic importance even before the Viking Age. Notably, large quantities of ash from massive fires have been discovered at the site, although their origins remain unclear. The Troldborg Ring provides valuable insights into the defensive strategies and socio-political turbulence of Late Iron Age Denmark.
