Finland has completed roughly 200 kilometers of new fencing along strategic sections of its border with Russia, strengthening security along one of the European Union’s longest frontiers with its eastern neighbor.
Rather than covering the entire 1,340-kilometer border, the barrier has been installed in areas considered particularly vulnerable to unauthorized crossings. Some sections stand about 4.5 meters high and are supported by surveillance cameras, sensors and barbed wire, giving Finnish border authorities greater ability to monitor activity in the area.
The project comes nearly three years after Finland closed its land crossings with Russia in December 2023. The decision followed the arrival of more than 1,300 migrants who reached Finnish border checkpoints without the required visas or travel documents.
Although the situation at the border has since become considerably calmer, Finnish officials say the risk of sudden changes remains.
Interior Minister Mari Rantanen said the current situation was calm but still tense, warning that authorities could not predict what might happen next.
“Things can change very quickly, so we have to be fully prepared,” Rantanen said near the closed Nuijamaa border crossing in southeastern Finland.
Helsinki has previously accused Moscow of deliberately facilitating the movement of third-country nationals toward Finland as part of what Finnish authorities described as “hybrid warfare.” Russia has rejected those accusations.
The fence is intended to serve both as a physical barrier and as part of a broader surveillance network. Finnish authorities say it will improve their ability to detect movement near the frontier and, when necessary, prevent unauthorized entry into the country.
The project also reflects Finland’s broader transformation in security policy since Russia’s full-scale invasion of Ukraine. After decades of military non-alignment, Finland joined NATO in April 2023, significantly reshaping its defense relationship with Russia.
Other countries along Europe’s eastern frontier have taken similar steps. Latvia, Lithuania and Poland have constructed barriers along their borders with Belarus, while Estonia has also strengthened security infrastructure along its border with Russia.
