- The Base XV was a really small one. It contained only position 1 and position 2, along with a cave, which is still standing, although in modern use. With only two defensive positions, this was in the "so-called" first line and would have been first to come in contact with the enemy.

- Keeping that in mind, the positions have been spread out rather strangely. This position 1, is located in the Manor of Tuomarinkylä and the position 2 is located South from the Manor area, the distance being somewhere around 1 kilometer.

- So with that kind of arrangement, position 1 would have been forced to fight alone any battles, as there's really not enough supportive positions, at least not so many as you can find from nearly any other areas of Viapori. One option is, that this position 1, was only meant to slow down the enemy and after that they would have faced the position 2 in Lystikukkula, which is much better supported by other close by positions.

- In any case, today the remains from the defensive positions are located right in the yard of Tuomarinkylä Manor and you need to behave, when you walk there, even when the place is open for tourists. The small patch of forest where the positions are, is really overgrown with nettles and other nasty plants. Also the fact that there's people living nearby, makes it today hard to tell, which constructions dates from Krepost Sveaborg time and which have been build after that.

- The forest contains a very strange "hill", which has been clearly build there. For some reason inventory does not say anything about this, but anyone who climbs on top of the hill and wonders the new hatch, which lead to somewhere, can seen that the hatch has been attached to the so familiar green concrete, meaning of course concrete to which moss has already grown. So it's quite clear that the construction is from Viapori, but another thing is, what it has been? There is only two holes on top of the hill and that's it, no doors nothing. I would suspect, that the doors have been either buried underground, or then the hatches on top of the hill, have provided access to this shelter or similar stucture.

- You be the judge, that what the hill has been, when you look at the pictures...

- Structure type, which I have not seen before. This most likely is a shelter. The roof is obviously missing, but the walls are still standing, although just barely.
