- The construction of the base XXIII was started in 1915. This position contains only trenches and few pits in the rock and it seems that when the construction ended, the position was not really completed.

- However, position 1 contains also an large shelter, which is still mostly intact even when the iron reinforcements have been blown off. The shelter has sustained the explosion remarkably well, with only the roof collapsing on top of the supporting walls. Interiors can be easily visited, just as long as you find the place.

- This shelter contains something which I though was impossible to find from Krepost Sveaborg anymore. Meaning original Russian text. Yes that's right, the roof of the shelter contains Russian text, or actually a one letter and a number, which has been engraved to the concrete. There's also other markings, but only from the Russian text you can be absolutely sure, that it was engraved there during the construction. Pictures from these markings and text can be found from the second page of this gallery.

- The books telling about the time of the First World War in Finland, contains quite a many notes about Krepost Sveaborg. The following informal translation is an citing from the book: Diary of a Red Guardsman (Punakaartilaisen Päiväkirja) by Viljo Sohkanen. He joined the Red Guards at the age of seventeen, participated to the battles in the area of Vyborg as a medic and was finally captured in the area of Tikkurila by the advancing Germans and White Guards. Text in the closures are comments from the translator, meaning me:

" In the railway station of Kvantsaari stands a train, ready to transport the Russian soldiers back to home, to St. Petersburg. Antropoff stands in the group. He's the same pioneer with whom I was connecting the telephone lines in the bunkers of Malmi and Herttonääs (Bunkers in Krepost Sveaborg, Herttonääs = Herttoniemi).

- The shelter can be spotted from the distance, even when time has camouflaged the whole place quite nicely and now it resembles more like the other rocks in the forest.

- The interiors which are still in a relatively good condition, when you think that iron was collected from the place with explosives. The storage holes are still visible in the wall.

- One of the large pits in the area.
