Conny Waters – AncientPages.com – The Vikings are commonly associated with raids and aggression, often seen as fearsome invaders across Europe. However, recent research reveals another side to their story. The Vikings themselves lived under the constant threat of enemy attacks and were highly prepared for warfare on their own soil.

For the first time, researchers have mapped out the Vikings’ defense system. This extensive network included a sophisticated warning system designed to protect against intruders. The system relied on signal fires or beacons placed in elevated locations throughout the landscape, allowing communities to quickly alert one another of approaching danger.
Vikings’ Beacons
During the Viking Age and Early Middle Ages, Norwegian Vikings were frequently concerned about potential attacks from neighboring Danes or Swedes. To address this threat, coastal beacons were strategically placed throughout Norway. These warning fires served as an effective early alert system, allowing signals of impending attacks to be transmitted over long distances. When a beacon was lit, it signaled the local population to prepare for defense and quickly mobilize their warships.
While Danish armies represented the main external threat during this period, internal conflicts also posed dangers. Political rivals within Norway could also become enemies, making the beacon system an important tool for both external and internal security.
Although beacon fires are among Norway’s oldest military traditions, having been in use from approximately 950 to 1814, they have received relatively little attention from researchers.

“This is surprising, both given their importance and the fact that they’re mentioned in many historical sources. A lack of knowledge and research on beacons has meant that these cultural monuments have been neglected in Norwegian cultural heritage,” says Marie Ødegaard in a press release.
She is an associate professor at the University of Stavanger’s Museum of Archaeology. She has led the research project Viking beacons – Militarism in northern Europe.
“Mapping and dating the beacons sheds light on the frequency and geographical extent of conflicts in the Viking Age, and thus the level of militarism in society, which appears to have been high,” she says.
Fear Can Unite People
Researchers have examined the impact of emotions on domestic defence systems. Their findings offer a more nuanced understanding of the Viking Age, shedding light on how emotional factors shaped defensive strategies during this period.
“The traditional perception is that it was a one-sided warrior society focused on outward attacks and violence. Our findings show that Viking society was also concerned with protection, safety, and community,” Ødegaard says.
Understanding how fear and emotions influence decision-making is key to understanding any society, she points out.

“We see this again today, as European societies face growing threats and fear. Our results provide a basis for discussing the extent to which war and fear increased preparedness and led to societal change in prehistory. Fear can unite people in common defence, but can also be used deliberately to manipulate,” she says.
Reconstruction And Identification
The project’s achievements are both impressive and significant. By successfully mapping beacons and guard houses, as well as reconstructing beacon systems from the late Viking Age, researchers have unlocked valuable insights into early warning networks. Their comprehensive approach—integrating archaeological evidence, historical documents, and place names—has enabled the identification of ancient beacon sites with remarkable accuracy.
Moreover, the discovery of boathouses potentially used for storing warships adds another layer of depth to our understanding of these administrative districts. The sheer number—approximately 300–500—of place names that reference beacon fires underscores just how widespread and organized this system was. Sites like Vigdelsveten near Stavanger, Vettakollen in Oslo, and Veten on Altøya near Bergen provide compelling physical evidence; multiple layers of charcoal found at these locations confirm their long-term use for signaling.

The use of radiocarbon dating (C14 dating) further strengthens these findings by pinpointing when these beacons were active. Collecting core samples from lakes allowed researchers to extract charcoal dust deposited by historic beacon fires—a method that offers precise dating capabilities.

Finally, through thorough data analysis, researchers have been able to estimate the effectiveness of this historical beacon system in alerting local populations. This multi-faceted research not only deepens our understanding but also convincingly demonstrates how sophisticated early organizational systems were—and why continued study is so valuable.
You Can Also Help Find Beacons
An online citizen science database lets people share information about possible archaeological remains, like old stone beacons or guard house ruins.
“Anyone who discovers structures that might be remnants of beacons can register their finds here. The goal is to prevent these remains from being built over or disappearing entirely,” says Ødegaard.
