After iv years, the earthworks of the famous Viking fortress, Borgring, is coming to a unopen in addition to archaeologists tin toilet straight off pull the fortress inwards a broader perspective: An anti-Viking defence forcefulness that allowed the Danish King to forge a new, mobile army.

The tidings travelled around the world, in addition to since in addition to then our excavations attain got continued to cast novel lite on the Viking Age.
Thousands of visitors attain got flocked to the site, which has been opened upward each summertime every bit a living museum. But if you lot desire to view in addition to then you lot volition take away to live quick, every bit this summertime volition in all likelihood live the lastly yr of excavations at Borgring.
Here are some of the most of import in addition to surprising discoveries made during the excavations. These finds non but say us nearly the history of the fortress, but also nearly the operate of these unique, band fortresses.
A “new” band fortress?
Borgring is i of five, large band fortresses from the Viking Age inwards Denmark. Each of the large fortresses were constructed inwards a perfect circle in addition to are some of the best known monuments left past times the Vikings.
The other fortresses include Trelleborg, Fyrkat, Nonnebakken, in addition to Aggersborg, every bit good every bit Borgeby inwards Southern Sweden. All were built past times King Harold Bluetooth who reigned betwixt circa 958 in addition to 987 CE in addition to is best known inwards Kingdom of Denmark for erecting the Jelling Stone—a large rock amongst the source written reference to the bring upward “Denmark,” oftentimes referred to every bit Denmark’s nascency certificate.
It had been threescore years since archaeologists had discovered such a band fortress inwards Kingdom of Denmark when nosotros finally found Borgring. Many doubted that it was indeed a Viking fortress, piece others claimed that the fortress had been known nearly for some time.
Locals retrieve an officeholder from the Danish Air forcefulness spotting the outline of the fortress inwards 1970, inwards aerial photos. He contacted the National Museum of Kingdom of Denmark who investigated the site in addition to concluded that at that spot were no Viking remains. People thus knew nearly the one-time earthworks inwards a acre due north of Lellinge, but archaeologists did non connect it to Harold Bluetooth’s fortresses.
Discoveries started to plough up
But the critics came around, every bit the results of the excavations started coming in. Among the most of import results, which ScienceNordic has previously written about, are.
1. Carbon-14 dating, which placed the fortress inwards the early on 900s.
2. Later discoveries of a Viking toolbox, buildings, ceramics, in addition to beads in addition to jewellery, indicating activities inwards the fortress.
In May 2018, Aarhus University together amongst the Danish Agency for Culture in addition to Palaces, held a conference on the Danish Viking Age band fortresses, which are to live nominated every bit UNESCO public heritage sites. It was clear that fifty-fifty the researchers who had been sceptical, were no longer inwards whatsoever doubtfulness that Borgring was i of Harold Bluetooth’s fortresses.
A network of fortresses
Since 2016, scientists from Museum Southeast Denmark, the National Museum of Denmark, in addition to Aarhus University, Denmark, attain got excavated the site, amongst funding from the A.P. Møller Foundation in addition to Køge Municipality.

Many attain got tried to explicate what operate the network of fortifications served. Here, it’s of import to inquire the correct questions, every bit the challenge is to regain an explanation that best accounts for everything that nosotros know nearly these fortresses.
Big fortifications, curt lifespan
The band fortresses but existed for a curt component of the Viking Age. Two of the best dated fortresses, Fyrkat in addition to Trelleborg, expression to attain got been established betwixt 974 in addition to 981, in addition to finds from the other fortresses suggest a similar date.
No other large fortifications existed inwards Kingdom of Denmark inwards the residue of the Viking Age, from the halt of the 700s upward to 1000s, except for metropolis walls inwards Hedeby (in modern twenty-four hr menstruum Germany), Ribe, in addition to Aarhus.
Chieftains in addition to kings built large halls in addition to farms, but non fortresses.
Four hypotheses for the Viking fortresses
Why did Harold Bluetooth build 5 fortresses inwards the 970s? This is the key query that has bothered Viking researchers since the fortresses were source discovered. So far, iv main hypotheses attain got been floated:
1. Training camps for the Viking regular army that conquered England around the fourth dimension of Sweyn Forkbeard. This hypothesis was shelved inwards the 80s, when dendrochronology revealed that Trelleborg in addition to Fyrkat fortresses were built in addition to used decades earlier the large laid on on England.
2. Fortified centres of violet command built past times Harold Bluetooth to subdue the population inwards the newly united Denmark: This was the dominant hypothesis for many years, but the dates i time again did non fit. Why would Bluetooth build the fortresses inwards the later on component of his reign, long after he became manly someone monarch around 958 CE, in addition to long after he declared Kingdom of Denmark a Christian Blue Planet inwards 963 CE?
3. Military bases during the grapple betwixt Bluetooth in addition to his son, Sweyn Forkbeard: Bluetooth’s boy rebelled against his father, but if the fortresses were built around 975, this rebellion must attain got lasted to a greater extent than than a decade across the entire country. Again, it didn’t fit.
4. Influenza A virus subtype H5N1 final result of an extraordinary unusual policy situation: Early inwards Bluetooth’s reign, a novel ability was growing from key Europe nether King Otto I, who was crowned emperor inwards 962. Otto’s growing ability was in all likelihood a crucial constituent inwards Harold Bluetooth’s conversion to Christianity, to avoid becoming Otto’s side past times side target. Many researchers attain got come upward to the conclusion, that it was the unique laid of challenges posed past times this province of affairs that led Harold Bluetooth to build the fortresses. Let me explicate why.
A network to defend against Viking attacks
Otto I died inwards 973 in addition to was succeeded past times his son, Otto II who attacked Danevirke (in what is modern twenty-four hr menstruum Germany), upping the threat to Harold Bluetooth’s Denmark, which remained a target for state of war until Otto II’s expiry inwards 983.

But a mystery remains: If the threat was from Germany, why were they built so far from the Danish-German border, on the isle of Fyn in addition to Zealand, in addition to Skåne inwards southern Sweden?
In 2014 I position forrad some other version of this “invasion theory,” together amongst my colleague Else Roesdahl. We suggested that the shrewd danger in all likelihood came from Otto II, which explained the timing of the fortress construction.
But some other constituent tin toilet explicate the distribution of fortresses around the country: The threat from the southward left Harold Bluetooth exposed to other threats from elsewhere, specifically from Kingdom of Norway in addition to Sweden, who mightiness endeavour to exploit the king’s weak position.
And so fortresses were established correct across the kingdom. They was a coastal defence: Rather than existence Viking fortresses, they were genuinely “anti-Viking” fortresses.
A novel theory
It was this hypothesis that led us to regain Borgring. It suggested that Harold Bluetooth must also attain got had a fortress to protect the eastward coast of the country, which turned out to live the case.
What nosotros couldn’t explicate was, how exactly the fortresses were used every bit a defence. And this is where the discoveries made at Borgring tin toilet shed some novel light.
With this inwards mind, nosotros tin toilet advise a novel explanation for the fortresses, in addition to a to a greater extent than straight connector betwixt Harold Bluetooth’s grapple on the southern borders in addition to his take away for coastal defences inwards the residue of the country.
Built inwards a hurry
The excavations at Borgring attain got revealed a fortress built to the same pattern every bit Trelleborg in addition to the other band fortresses. We also come across that the fortifications were good planned in addition to completed swiftly.
The landscape was levelled, in addition to the walls were built inwards a precise circle, amongst gently sloping sides within the fortress. The interior is divided into fifty-fifty sections, amongst iv wooden gates placed at exactly xc degrees to each other.
But then… nothing. There’s no sign of repairs or extensions to the walls, at that spot are but feeble traces of wooden constructions, which could attain got supported a high wall, in addition to dissimilar Trelleborg, Fyrkat, in addition to Aggersborg, at that spot are no signs of structure inwards the interior of the fortress.
But at that spot are traces of a damaging give the axe inwards numerous places around the fortress, in addition to deep cycle tracks that suggest long-term utilization past times traffic coming inwards in addition to out.
A fortress for refugees
How tin toilet nosotros explicate these features? It is possible that the structure was interrupted prematurely, but inwards this illustration nosotros mightiness attain got expected to come across to a greater extent than clear traces of the edifice process, in addition to nosotros wouldn’t hold off to come across whatsoever later on activity.

Looking at the earthworks drawings from Trelleborg made inwards the 1930s, nosotros come across that the fortress walls were built upward numerous times, amongst the oldest stage most similar to the walls at Borgring.
And Borgring is non alone: One of the other fortresses, Nonnebakken, does non seem to attain got whatsoever interior buildings either. This suggests, that the primary role of the fortresses was non to identify a permanent settlement, but to allow people to flee at that spot for curt periods of time.
This role every bit a identify for refugees to seek shelter, points to a novel in addition to stronger connector betwixt the fortresses in addition to Harold Bluetooth’s was against Otto II.
Fortresses sent warriors to the southern border
The state of war amongst the southward meant that Harold needed to telephone phone upward reinforcements from all of the supporting chieftains to assemble warriors along the southern border.
Such an functioning was described inwards the Skaldic poesy form Vellakla, written every bit a praise poesy form to the Norwegian Earl Hakon, a contemporary of Harald Bluetooth. According to the poem, Hakon was summoned to assistance Harald’s fighting at the Danevirke.
This left over parts of the Blue Planet without the warriors who would unremarkably defend them in addition to exclusively unprotected. In fellowship to win the state of war amongst the south, Bluetooth had to offering some other shape of protection to these areas, thence the fortresses.
Placed on plough over of a fortified wall, it was possible for a poorly armed in addition to untrained person, human or woman, to grapple off a well-trained warrior.
If plenty people sought refuge inwards the fortress, in addition to then the attackers were unlikely to attain got it. They could initiate a siege, but fourth dimension would live against them.
A successful strategy
The fortresses offered protection to locals, inwards the absence of the warriors who had live called upward to protect the south. This allowed locals to withstand Viking attacks, in addition to provided Harold Bluetooth amongst a mobile regular army that he could deploy to the High German border.
The fortresses were intended to deter potential attackers, past times allowing the local population to seek shelter in addition to defend themselves.
Seen this way, the fortresses are no longer a mystery. In fact, they successfully fulfilled their mission.
Harold Bluetooth strengthened his ability base
Constructing the band fortresses, allowed Harold to consolidate his ability throughout the kingdom inwards a way that no other manly someone monarch of Kingdom of Denmark had done before.
The large buildings of Trelleborg suggest that some of the fortresses came inwards due fourth dimension to attain got on a to a greater extent than active role every bit settlements or maybe wintertime camps for warriors. But source in addition to foremost, this network of fortresses allowed the manly someone monarch to exploit his master copy armed forces assets, warriors, to a greater extent than effectively.
These warriors did non human the fortresses, which were, on the contrary, a way of protecting the share of the population who were non warriors. This was a decisive countermeasure that allowed Harold to defend in addition to win the state of war inwards some other component of the kingdom.
Excavations at Borgring attain got revealed novel pieces of the puzzle to empathize all of Harold Bluetooth’s fortresses.
You tin toilet nonetheless pick out care of a glimpse of the excavations of the walls in addition to due west gate, earlier this footling slice of Viking Age Kingdom of Denmark volition live covered past times soil in addition to grass i time more.
