Russia is building new military bases and expanding existing ones along its northern border with NATO, according to ISW. The Institute for the Study of War (ISW) assesses that the construction likely supports future Russian force projection against the alliance. Near-term Russian ground operations remain unlikely, the think tank notes, since most Russian combat power stays committed in Ukraine.

Broadcasters in Norway, Sweden, and Denmark, together with a Baltic news portal, published satellite findings of the buildup on 10 June. Russian forces are putting up new facilities and growing old ones near the frontiers of the Nordic and Baltic states. Intelligence officers and senior commanders in Denmark told broadcaster DR the work amounts to preparation for conflict. They see nothing indicating Moscow has actually decided on war, not least because the bulk of its army remains tied down in Ukraine.

Finland braces for 80,000 Russian troops at its border

Marko Eklund, a former Finnish intelligence officer, told DR that the Russian command plans to deploy about 115,000 troops at the northern NATO border. That deployment would come after the war in Ukraine ends. Construction has begun on a new Russian base at Novaya Vilza, outside Petrozavodsk in the Republic of Karelia. The site sits roughly 190 kilometers from Finland and will hold 4,000 to 6,000 personnel. Russia began renovating an abandoned Soviet-era garrison in Petrozavodsk earlier this year. Finland's army chief, Pasi Välimäki, expects Russia to put 80,000 soldiers on the shared border, he told Swedish broadcaster SVT.

A corps command waits in Luga as Karelia bases rise

A source covering the Russian Northern Grouping of Forces claimed Russia's command is moving parts of the 44th Army Corps, a Leningrad Military District formation, to the Republic of Karelia. Only the command post stays behind for now. Those command-post elements currently sit in Luga, Leningrad Oblast, ready to shift to Petrozavodsk once Russia finishes the bases, the source claimed.

A Kremlin-affiliated Russian milblogger claimed on 11 June that crews are upgrading at least 19 barracks, along with support and storage buildings, at Pechenga on the Kola Peninsula in Murmansk Oblast. The site lies about 10 kilometers from the Norwegian border. The milblogger also claimed Baltiysk in Kaliningrad Oblast is getting a bigger naval infantry footprint, more armor, and additional landing craft.

ISW: bases serve post-war force projection

"Russia is establishing these bases to support potential future military actions against NATO, though such ground operations remain unlikely, as most of Russia's combat power is participating in operations in Ukraine," ISW says.

Once the shooting in Ukraine stops, the finished bases would shorten Russia's timeline for massing troops at NATO's frontier, ISW assesses. That leaves NATO needing the readiness to hold off — and, failing that, beat back — a Russian threat at its borders soon after combat in Ukraine stops, in ISW's assessment.

Archaeologists in Denmark are recreating a puzzling Iron Age feature to understand better its purpose more than 2,500 years after it was built. Known as hulbælter in Iron Age, or “hole belts,” the structures consist of long rows of shallow pits that stretch across the landscape.

Dating to around 500–300 B.C., some extend for hundreds of meters, while others run for several kilometers. Researchers have identified nearly 50 examples across Denmark, particularly in central and western Jutland. Despite decades of study, archaeologists still do not know exactly why the pits were dug.

Hole belts remain one of Denmark’s oldest mysteries

The pits are not graves, ordinary postholes, or waste pits. Instead, they form organized belts three to six meters (9.8 to 19.6 feet) wide, with individual holes typically measuring only 30 to 40 centimeters (0.98 to 1.3 feet) deep.

Similar features have been reported in Sweden and the Netherlands, but they are far more common in Denmark. Their unusual layout suggests they were built for a specific purpose rather than as isolated features.

To investigate, researchers at the Saxo Institute at the University of Copenhagen have launched a large-scale experimental archaeology project.

Researchers rebuild an Iron Age landscape

Led by associate professor Henriette Lyngstrøm, the project brings together 30 archaeology students at Sagnlandet Lejre, an open-air research center and reconstructed Iron Age village.

The team is rebuilding a hole belt from scratch using reconstructed tools and ancient techniques. Researchers are measuring the time, effort, and coordination needed to create the features. The goal is to move beyond theory and test how the belts may have functioned in everyday life.

Digging reveals the scale of Iron Age labor

One part of the project focuses on reconstructed wooden spades based on Iron Age finds. Archaeologists once thought some of these tools may have been paddles. However, traces of soil, stones, and wear patterns suggest they were used for digging.

Tests showed that wooden spades could create the pits, but the work was slow and physically demanding. The tools also required frequent sharpening.

The findings indicate that constructing long hole belts would have required planning, organization, and coordinated labor. Researchers say such projects likely involved leadership and cooperation within Iron Age communities.

Food storage theory gets a real-world test

Researchers also examined whether some pits could have been used for storage. Graduate student Angelyn Sørensen placed a chicken inside a ceramic jar buried in a reconstructed pit. On a day when air temperatures reached about 20 degrees Celsius, the meat warmed only slightly, rising from around 10 to 12 degrees.

The results suggest that covered pits could help moderate temperatures, although the experiment does not prove a storage function.

Experiments test the defensive barrier theory

The strongest results came from tests of the defensive theory. Earlier studies showed that sheep and cattle could cross similar pit zones without difficulty. However, when researchers staged mock combat exercises, the pits made movement more difficult for attackers.

Participants struggled to maintain balance, move quickly, and fight while crossing the uneven terrain.

Researchers stress that no single explanation has been confirmed. Still, the experiments show that the hole belts were carefully planned features that required labor, organization, and a clear purpose. Their exact role remains uncertain, but the project is bringing archaeologists closer to understanding one of Denmark’s most enduring Iron Age mysteries.
