Finland completes 200-kilometer security fence along Russian border

Border barrier completion

Finland officially completed a 200-kilometer fence along its eastern border with Russia on 7 September 2026. Interior Minister Mari Rantanen presented the finished structure during a media event near the Nuijamaa border crossing in southeastern Finland. The installation stands 4.5 meters high, features barbed wire along the top, and incorporates electronic surveillance cameras and motion sensors.

Rantanen described the security barrier as a necessary step to safeguard national borders following changes in European security after February 2022.

This is one part of our border security and it is helping us for surveillance, but also keeping people out of Finnish territory if needed.

Project costs and regional allocation

The construction initiative required extensive coordination with approximately 1,000 private landowners and hundreds of commercial contractors. Border Guard project manager Erkki Matilainen stated that the total construction cost reached 356 million euros, with recurring annual maintenance estimated at 2 million to 3 million euros. Separate European media estimates placed the total expenditure between 350 million and 380 million euros. Matilainen noted that despite advances in drone surveillance, physical barriers remain the primary tool for crowd management along frontier sectors.

The 200 kilometers of fencing cover key segments along Finland's 1,340-kilometer land boundary with Russia. The largest portion extends roughly 140 kilometers across the southeastern border region. The barrier also includes approximately 35 kilometers in North Karelia and 25 kilometers divided between Lapland and Kainuu province, expanding outward from an initial pilot segment constructed near Imatra. Rantanen noted that Finland would assess whether further extensions are necessary and called for dedicated European Union funding for eastern member states.

Migration policies and border closure

The barrier project follows the Finnish government's decision to shut all passenger border crossings with Russia in December 2023. Helsinki enacted the complete closure after more than 1,300 asylum seekers from third countries, including Syria and Somalia, arrived at border posts without visas in late 2023. Finnish authorities accused Russian officials of orchestrating the migrant flows as hybrid warfare, an allegation the Kremlin rejected.

Markku Hassinen, chief of the Finnish Border Guard, stated that physical barriers are essential for field personnel handling irregular crossings.

Without a border fence, it is not possible to combat instrumentalised entry effectively, credibly and safely.

Broader regional security framework

The construction followed Finland's accession to NATO in April 2023, which ended decades of military non-alignment. Although border officials report that unauthorized crossings have dropped to isolated incidents since the 2023 closure, land checkpoints will remain closed indefinitely. Finnish lawmakers have also proposed extending the temporary Border Security Act until 31 December 2028, permitting border guards to turn away asylum seekers during state-sponsored migration operations. Similar fencing projects have been established along Estonia's border with Russia, as well as along borders shared by Latvia, Lithuania, and Poland with Belarus.
