About

Aggersborg is a significant archaeological site in Denmark, notable for being the largest Viking ring fortress in the country. It stands on the north side of the Limfjord and boasts a meticulously planned circular design with defensive ramparts and ditches. Constructed around 980 CE, during the reign of King Harold Bluetooth and/or Sweyn Forkbeard, it served as a strategic stronghold. The site was originally an Iron Age village established in the late 8th century before being cleared for the fortress. Aggersborg's archaeological remains include traces of 48 longhouses and a vast array of artefacts from both the Iron Age and Viking Age. The fortress was only used for a short duration, likely as a defensive or administrative outpost. In 2023, Aggersborg was recognized as a UNESCO World Heritage site, underscoring its historical and archaeological importance.
