On 11 June 2006 on the territory of the Finnish defensive complex in Medvezhegorsk the third military-historical festival "Karelian Borders" was held.

The festival was held on the mountain Lysukha, which is situated in the outskirts of town. The re-enaction of the "fight" was on the real defensive line of the Finnish troops of the Grate Patriotic War period.

After the town had been captured by the Finnish troops in December 1941, the headquarter of Finland faced a question to build a powerful fortification on its territory. In the middle of 1944 all the dominant hills, circling the town from 3 sides, had been turned into powerful command posts with numerous weapon emplacements, camouflaged by wire entanglements and mine-fields. Carefully masked defenses were presented by complex constructions, carved out in the rocks. The special sphere forms with holes for observing and shooting were in the upper side of the dugouts. It turned out, that the Medvezhegorsk defensive potential had not been realized: in June 1944 the town was won back.

The festival was organized by the local authorities of Medvezhegorsk district and the Medvezhegorsk local museum.
