Aggersborg Fortress

Today we are going to travel a little further into the past than normal, to one of the world’s greatest archaeological sites in the world. It belongs to Denmark and was originally a Viking trelleborg: Aggersborg. A trelleborg was what they would have considered a palace and this one is known to have been built by Harold Bluetooth (who is credited with introducing Chirstianity to Denmark) around 970-980 and was built atop an older village. 

A trelleborg was a vast area defined by a pretty much perfect circle used as a fortress. The roads and gates were determined by the cardinal directions. There are seven known throughout Denmark, Sweden, and Scandia. Aggersborg is Denmark’s largest.

Located strategically in between the Baltic and North Seas, the site was 240 meters in diameter and held 48 long houses for around 5,000 people. The houses looked almost like viking ships turned upside down and each consisted of around 66 oak trees. It is believed to have been the launching place for many of the Viking exploration into England and what is now known as northern Scandinavia, though the original purpose of this construction remains a mystery. 

The fortress burned to the ground in 1086 and while there were attempts to rebuild it over the next couple centuries, it was completely demolished in 1441.

Today it is used as a place for us to learn more about the elusive Vikings and their daily lives. You can visit the site and even download an app that helps visualize what the site looked like over one thousand years ago. 

We hope you enjoy this narrow peak into the infrastructure left behind shortly before the period we usually discuss!
