- The area of Skogbyträsket is a rather interesting one in a sense, that it is a foreground of the defensive line. The distance to the borderline of the Soviet rental area isn't more than a one kilometer in some parts of the area. The distance to the main defensive line where all the armed structures are located is about one to two kilometers. Despite of the fact that the distance to the borderline is so small, only one armed structure has been marked to the Skogbyträsket area. Additionally most of the accommodation bunkers/dugouts have been marked without the shelter for the anti-tank gun.

- The conclusion from this is, that these structures were marked to the map relatively late. Perhaps not until the summer of 1941, when it had become clear that the Russians are not going to attack too actively in the Hanko Cape area. Marking concrete fortifications to the foreground of the defensive line during the initial planning stage in 1940 would be a very strange thing. Why build concrete fortifications to an area, which would have been given up once the attack started, fighting a withdrawal battle at the same time before reaching the main line?

- Almost all of the numbered structures can be found from the area, but none of them are concrete structures. This would also support the assumption, that the structures were built and marked to the map later than 1940. There is also no signs about building concrete structures in the area.

- The best preserved dugout remains is the number 208. The dugout is located just beside the road and a sharp eyed person can notice it while walking or driving in the road. Other easily recognizable dugout remains are the numbers 204 and 220. Additionally the entrance to the structure 206 is visible to the road. The trees and bushes however have covered the structure remains, making it impossible to take a rational picture from the structure. The edges of the structure can be spotted by an sharp eyed passer by.

- One of the most interesting places is the area where the structure 209 is located. There isn't really no traces left from the structure. However a sub-section staff was located in the area of Skogby iron works which is located nearby of the structure 209. The staff itself was located in the mill. The mill is in a sad condition, with only the outer walls standing. There is no plaque reminding about the importance of the area during the war. The Skogby iron works is also a worth to visit, if you happen to be in the area. Additionally near of the former staff area is a remains from an war time sauna. The stove still lies at the bottom of the remains. No one probably can say with a full certainty, whether or not the stove dates from the wartime or not, but it is certain that there has been a sauna in that place.

- The code names for the bunkers are either Finnish man or female names or animals.

- My own personal notes below are based on the situation in the defensive line, during the years 2005 and 2006.
