In the shadow of Sweden’s rich historical tapestry lies a hidden marvel—Galärvegen, the overland route used by King Charles XII during the Great Northern War. Recently uncovered by archaeologists, this discovery sheds light on one of Sweden’s boldest military strategies and highlights the transformative power of modern archaeological techniques. The story of Galärvegen is a testament to both human ingenuity and the enduring mysteries of history.
The Bold Strategy of Charles XII During the Great Northern War
The Great Northern War (1700–1721) marked a turbulent period in European history, with Sweden under King Charles XII striving to maintain its dominance. In 1718, Charles XII devised an audacious plan to transport 12 massive war galleys, each weighing up to 30 tons, over 25 kilometers of rugged land. Known as Galärvegen, or the “Galley Road,” this route was integral to his strategy to surprise the Norwegian stronghold of Fredriksten Fortress at Halden.
Fredriksten had long been a thorn in Sweden’s military ambitions, repelling multiple attacks. By bypassing naval blockades at Iddefjorden’s entrance, Charles aimed to launch an unexpected assault from the sea. The logistics were staggering—800 soldiers used pulleys, hoists, horses, and greased logs to haul the ships across treacherous terrain. Despite the eventual failure of Charles XII’s campaign and his death later that year, the Galärvegen operation remains a symbol of military innovation and determination.

Rediscovering Galärvegen: The Archaeological Breakthrough
In December 2024, a collaborative team of archaeologists from the Norwegian Institute for Cultural Heritage Research (NIKU), Bohusläns Museum, and other institutions uncovered traces of Galärvegen in Blomsholm, Sweden. Initially seeking signs of prehistoric settlements, the researchers stumbled upon evidence of the 1718 route using the cutting-edge AutoMIRA georadar system.
The georadar revealed parallel straight structures, identified as timber logs laid to stabilize the ground for the heavy galleys. These traces spanned 160 meters, offering physical proof of the daring operation. “The survey revealed clear traces of the Galärvägen, which is undoubtedly one of the most exciting finds from this investigation,” remarked archaeologist Erich Nau, the project leader.
Bridging Past and Present: The Role of AutoMIRA Technology
The AutoMIRA georadar system played a pivotal role in the discovery of Galärvegen. Developed by NIKU in collaboration with AutoAgri, this autonomous radar system is designed for efficient large-scale surveys. At Blomsholm, the team covered 8.5 hectares in just three days, gathering high-resolution data that uncovered not only Galärvegen but also other historical elements, such as prehistoric burial mounds and settlement remains.
AutoMIRA’s ability to produce detailed maps of buried structures is revolutionizing archaeology. As Roger Nyqvist of Bohusläns Museum noted, “The discovery of Galärvägen allows us to combine historical sources with modern technology to explore and share significant parts of our shared cultural heritage.” This breakthrough underscores the potential of georadar systems to transform how we uncover and study hidden landscapes.
Insights into Charles XII’s Military Ingenuity
The discovery of Galärvegen offers fresh insights into the logistical and engineering feats of Charles XII’s army. Moving 30-ton warships over rugged terrain required not just manpower but also precision and innovation. The soldiers’ use of greased logs, pulleys, and hoists demonstrates their resourcefulness in overcoming the challenges of the landscape.
The route’s preservation through archaeological traces highlights the meticulous planning that went into its construction. It also reaffirms the importance of blending historical records with physical evidence to gain a fuller understanding of historical events.
Blomsholm: A Site of Layered Histories
Beyond Galärvegen, the Blomsholm site revealed a wealth of historical elements that paint a picture of human activity spanning centuries. Archaeologists found prehistoric burial mounds, ancient settlements, and signs of Blomsholm’s use as a field hospital during Charles XII’s campaign. Nearby, the remains of soldiers’ burials further underscore the area’s role in Sweden’s military history.
Interpreting the data from Blomsholm is challenging due to the overlapping layers of human activity. However, these complexities also enrich the narrative, highlighting the dynamic and multifaceted nature of the site’s history.
The Broader Implications for Archaeology
The rediscovery of Galärvegen marks a significant step forward in both historical research and archaeological methodology. By combining advanced technology with traditional fieldwork, researchers are unlocking hidden chapters of history that were previously inaccessible. The success of the AutoMIRA system in Blomsholm sets a precedent for its use in other large-scale archaeological projects, potentially revolutionizing the field.
For historians, the discovery provides a tangible link to one of Sweden’s most iconic military campaigns. For archaeologists, it demonstrates the value of interdisciplinary collaboration and technological innovation in uncovering and preserving cultural heritage.
Conclusion: Preserving the Legacy of Galärvegen
The story of Galärvegen is a reminder of the enduring impact of human ingenuity and ambition. King Charles XII’s bold vision, realized through the efforts of his soldiers, left a physical imprint that has withstood the test of time. The rediscovery of this hidden route not only enhances our understanding of Swedish history but also showcases the power of modern technology to bring the past to life.
As archaeologists continue to analyze the findings from Blomsholm, Galärvegen stands as a testament to the resilience and creativity of those who came before us. It is a bridge between the past and present, inviting us to explore the stories that lie beneath our feet and inspiring future generations to uncover the secrets of history.
