Östersolberg II



While I was travelling for work and fun for the last couple of weeks, Jarmo had scouted several bunker sites. His visit to an incredibly large bunker in Siuntio's Östersolberg provoked our interest as well, and last Saturday Janne, Olli, and me went there as well.

The bunker was indeed large, by my (foot) estimate the concrete shield on top was 19 m by 19 m. Jarmo's estimate from Google Maps was 20 m x 20 m.

However, it is far more difficult to say what's inside. On the top, the construction looks fine, with a central, large gun tower, two entrance tunnels from opposite sides, and a set of chimneys or air shafts to the side. As if the bunker had heating, or a kitchen? :-)

And one of the entrance tunnels is open enough for us to enter. However, the insides are so completely destroyed that we can't get particularly far. I was able to get near the central gun mount, but had no idea how to go towards the area that housed the air shafts, for instance. And I don't know how many floors the structure had. One, and the internal explosion that destroyed the bunker ripped the roof slab into two layers? Or two, and we're looking at a floor?

It is easy to go maybe 10 meters from the entrance tunnel, and you can peek towards the rest of the structure. But actually getting to the rest is the difficult part. There's nothing except a wall on the right side, the side where one would expect to find more rooms leading to the air shafts. On the left, towards the gun tower there's hanging floors/ceilings and twister rebar. I was able to sneak through an opening to take some of the pictures in this blog article, but it didn't feel particularly safe to go further.

Interesting place!

Coordinates: N 60.1133285 E 24.1211985.

Here's a picture of the space that the entrance tunnel leads to, the only easily accessible location.

On one side of the bunker there's a deep well, with stairs leading to the bottom. Used as an actual well? An emergency exit? Or for pumping water out of the bunker's base?


We also wanted to visit the Igor Museum (museum of Porkkala occupation) but it turned out to be cold during January:

Stubböle's Kasabergen Bunkers


Jarmo, Olli and me explored the Stubböle area on Sunday, and played around with drones. This area is in Siuntio, on the Soviet occupation area of Porkkala, and they seem to have had bunkers on every little hill around the fields.

That we are here was this time not due to Lynx's great database of Soviet occupation remains, but Jarmo's even greater work on mapping many sources from history books to Lynx and mapping services together. He now has the most complete database, easily usable with overlaid maps and aerial pictures from different times. This database helps him find places that wouldn't otherwise be listed in any easily available source! More on this important development in future blog articles, I'm sure!

In Stubböle, our first bunker exploration turned out nothing, we merely found the foundations of some kind of silo or container, possibly just farming related (coordinates: N 60.06289470 E 24.13498145).

But on the Kasabergen south of Stubböle, we found two bunkers. The first one to the north of Kasabergen greeted us with moose skulls in the gun mount hole. The normal entrance tunnel was blocked, so we had to enter that way. The bunker was almost completely filled with water, but I was able to walk inside on top of some rocks.

The coordinates for the northern bunker are N 60.06057076 E 24.13599132.

The second bunker more to the south had a different setup, with the gun hole largely blocked but the entrance tunnel still usable. Oddly enough, someone had dragged logs into the entrance tunnel, presumably to help walking on the muddy floor (?)

The coordinates for the southern bunker are N 60.05592067 E 24.13394410.

We also found an abandoned basement or storage room in the nearby woods, but as that may belong to someone I don't want to reveal the coordinates.

And we talked to the locals, who indicated that there's plenty more to look for, including a recently dug-up three-story bunker. Interesting!

NOTE: WARNING! Please remember that old ruins and particularly military bunkers and any underground facilities are potentially very dangerous. Not for kids, not for adults, not for anyone. I don't recommend that you visit any of these sites.

It always pays to smile, no matter what the situation?


And then to the southern bunker. We found some "carrots" under the ice:

We also found an oddly coloured rock:


Here's the bunker we did not find, just found the remains of some container:

EuroSpeleo!


After some prodding from friends in the Finnish Caving Society, I finally decided that I should travel to my first caving conference, the EuroSpeleo!

This will be happening in Ebensee, Austria, August 23-26, 2018. Registration is now open!

Einstein Museum



Einstein museum! I did not know there was one in the world. As we were returning from Interlaken with Janne, stopping at the museum in Bern was easy.

We saw Einstein's passport and found out many things about Einstein that at least I didn't know, about his family, his support of refugees (as a refugee himself). Something to think about for today...

Siuntio Östersolberg


Another guest blog entry from Jarmo:

I have done some Bunker hunting with kids during the last few weeks. In December I did a walk in the forest with Eino. First we visited a natural cairn that was in a list of prehistoric sites maintained by National Board of Antiquities (Museovirasto). It was a rather large (70 x 20 meters) flat pile of rocks. The site is located at N 60.15126045868919 E 24.441075770066867. From there we continued to a Soviet rental period bunker that was listed in Kirkkonummi orienteering club Lynx database. The bunker was in a relatively good shape although the gun hole at the top was blasted and filled. It was a standard small size bunker and easy to enter through a long entrance corridor. The bunker is located at N 60.1523370923527 E 24.439182130502353. We parked the car at Dalkullantie road and it was a very nice forest walk from there.

Next trip was early January with Eetu. This time we went to a city of Siuntio which is not that well covered in Lynx database. We got the coordinates from a book ‘Pekka Silvast, 1991. Porkkala 1944–1956 - Neuvostoliiton merisotilaallinen tukikohta. Tutkimusraportti, Sotamuseo 1/1991’. It has some maps that show potential bunker locations. We went to check four sites east of Solberg, Siuntio. The first site we checked was  just next to a Knapantie but we did not see any sign of a bunker (at N 60.11358185466233 E 24.137855058724238). The second site was not far at the edge of a farming field and this time we did find a bunker (at N 60.11477465670625 E 24.129049366528346). It was fully covered and only the gun hole at the top was slightly visible. No way to enter it so we moved on to the next stop further west (at N 60.113831778668214 E 24.12245113235171). Again no bunker there even though we did find a piece of concrete slab that could be from a bunker. By the way, the whole forest area just next to a farming field seem to have an old trench that runs for hundreds of meters.

We kind of thought that we are done and we could not find a decent bunker to enter. But then we checked the last bunker site of the day and found a really big one. It is one of the biggest that we have found so far. Unfortunately I did not make any measurements but it is visible in Google satellite image and from there I measured that it could be as big as 20 x 20 meters. In the center it has a big filled round hole which is likely a gun hole. On the side it has an entrance corridor that was only partly filled and easy to enter. The inside of the bunker was blasted pretty badly but it used to have two floors. This big bunker is located at N 60.11332858748937 E 24.121198540741755. This time we did not get a nice forest walk because forest logging was done just recently. We ended up walking next to a farming field which was also pretty nice.

In addition to those trips I did a quick walk in Kirkkonummi very close to Espoo. I managed to find one bunker that was filled and barely visible (at N 60.149212554762876 E 24.581357983754764). It was not possible to enter the bunker.

Barry, the dog


Janne and I were in Switzerland, and we met Barry, the famous St. Bernard dog.

Or at least, Barry after he was processed by the taxidermist in 1814... his body is preserved in the Bern Museum of Natural History.

What a wonderful dog. The prototype for what became the famous brand; and he must have been a welcome sight for lost mountain travellers.

Cosy Bunker


For sale: cosy apartment with flower decorations, strongly built, safe and in the middle of nature. In good condition. Also largely underground and abandoned 100 years ago.

A bunker. A concrete fortress.

I was once again in Stockholm for work. I had originally planned to take my skis for some evening visit to a local ski area, but it turned out that all the Stockholm area ski areas were closed. ("Snow depth: 0 cm Avalanche danger: 1/5"). So I threw in a headlamp and hiking boots to my bag before heading out to the airport, just in case I'd be able to find some bunkering or small cave exploration to my trip.

But once again I didn't have much time. But I had had a late conference call one night, so I felt like I could show up at work a bit later the next morning and explore a bit while it was still daylight. However, I didn't have more than half an hour for the exploration. The clock was ticking, and I was not finding what I was looking for, the Lugnetfortet bunker in the Korvlinjen, near Arninge and Täby, north of Stockholm.

I did find trenches. And I found a pile of sewer pipes abandoned in the forest. But no bunker. And the trench had clearly been placed in the most defendable place at the top of the hill, defending against threat from north. Yet, nowhere nearby I could see the bunker.

I was already resigned to go back to the car, when I realised that the bunker was in fact towards the defence direction from the trench, and on a lower-laying area. Odd, but I had found the bunker. Compared to the other Korvlinjen bunkers, this one was more overtaken by nature, almost invisible even close by.

But inside, pristine concrete from 100 years ago, smooth lines. And painted, with graffiti.... and with flowers. Most of the Korvlinjken bunkers form a T structure, with the main defence/gun positions at the two ends of the top of the T. Here as well. But the gun window of the right side end had been partially masoned closed. Originally or as a later modification? I don't know, but to me it looked like somebody might have been living in this room in recent years. Now empty, but the walls were painted well, there was a heave door that could be closed...

The trenches are at N 59.45668968 E 18.13571178  and the bunker itself is at N 59.45757424 E 18.13680672. This is nearby the two bunkers I had previously been looking for in Arninge (and only one of which I found; I have yet to find the Östra Arningefortet.)
