Breakthrough in dating Viking fortress

In 2014 archaeologists discovered the previously unknown Viking fortress at Borgring south of Copenhagen. Since then the search has been on to uncover the life, function, destruction and, not least, the precise dating of the Viking fortress. Now a new find has produced a breakthrough in the investigation.


The carved oak timber object recently found in peat layers just outside the south gateway of the fortress. The piece has been cut and sampled for dendrochronological sampling (left). The function of the piece is unknown, but it may be a part of a door or building.

In the period 2016-18 a programme of new excavations is made possible by a grant from the A.P. Møller Foundation. The team from the Museum of South East Denmark and Aarhus University are joind by leading experts from the Environmental Archeology and Materials Research at the Danish National Museum and the National Police Department's Section for arson investigation. Prior to this year's excavations it was only known that the massive, 150m wide fortress dated to the tenth century. Experts suspected that it was built in the reign of Viking king Harold Bluetooth (c.958-c.987), but the association could not be proven.
On June 26, the archaeological team opened new trenches is the meadow next to the fortress to search for evidence of the landscape surrounding the fortress. Around 2.5 meters below the current surface of the valley was found a c. 1m long piece of carved oak wood with drilled holes and several wooden pegs in situ. The wood carries clear traces of wear, but it is not currently possible to say what function the wood piece has had.
