This is one of the larger "million" bunkers with many underground rooms, all relatively well preserved. The bunker is located some 1 kilometer east from Vyborg highway, and this is why it remained intact during the combat - the 100th Rifle Division of 7th Army attacked along and to the west from the highway, with Sk2, Sk5 and Sk6 taking the main toll of the offensive.

Entrance to the western casemate of the bunker:

The bunker had the front casemate walls built from armor. This allowed for lower silouette of the bunker and easier camouflage. The armor of Sk10 consisted of three armor plates bolted together with some space between them. Just like all other metal parts that could be taken away, the armour plates were dismounted from the bunker after the war for scrape metal. Remains of armor on the eastern casemate of Sk10 can be seen in the picture below. There is also an empty body of old 203 mm shell lying next to the remains of armor plates. Someone took the grenade away for a souvenir or scrap metal in summer 2003. The grenade weighted about 60 kg.

Another unique item of the bunker is the Maxim machine gun mount designed by Liet. Col. Fabrizius and installed in the central part of the bunker as an experiment. The mount allowed to hide the machine gun inside the bunker and to pull it out into firing position when necessary. The mount is almost intact.

The bunker was blown up several times after the war, but it did not cause any substantial damage to the underground corridor and the barracks - the underground corridor is completely collapsed only in one place, immediately next to the eastern casemate. The rest of the indoor bunker rooms are well preserved and should definitely be seen if you are visiting the Summa village defence sector.
The corridor wall on the left is bent inside the bunker by the explosion. Note the burnt wooden parts of the walls - this means that the Finnish garrison burnt the bunker when retreating in mid-February 1940.

The staircase to the underground barracks from the western MG casemate. The length of the staircase tell the depth at which the underground barracks are located. If you are going inside the bunker, do not fall in the well, which is well preserved in theis bunker, is deep and always full of water. The bunker is in such good condition due to the fact that Red Army units undertook almost no assault attempts against this bunker.
Fragment of war diary of the 2nd MG company, 15th Infantry Regiment, which manned the bunkers in Summa village from Dec 3, 1939 to Jan 3, 1940. Entry for Dec 23:
"...The night was quiet. During the day - the same noise as the pervious days. Nerves of garrisons in Bunkers No 3, No 5 and No 6 under enemy's fire are stretched to the limit - the accommodation chambers in those bunkers are old and weak; they will not stand against a direct hit by grenades of such caliber. Bunkers No 10 and No 17 on the other side of the highway are left alone, at least for now..."

Remains of barbed wire fence halfway between Sk10 and Sk17 bunkers. They burnt in summer of 2006 during massive forest fires.
