Bunker on the Tulikukka Alley


I used the "Parenteesi Suunnistuskartalle" database from Lynx and coming home from work, stopped at bunker location in Sarvvik.

Not much to be explored, really. A fenced 5x5m area, with concrete covering what holes they may have been earlier. Outside the fenced area, a rectangular depression leading to the fenced area. Most likely, this was the entrance tunnel which has been destroyed.

Just outside the fence, there was a wall still visible in the ground, and in the depression... there might be some opening to explore, although it is perhaps unlikely. Too much vegetation, not the right clothes for exploration, and being alone, I didn't want to push it.

The place is near the roundabout between Sarvvikintie and Sarvvikin Puistotie, and near Tulikukkakuja. Coordinates: N 60.15354417 E 24.60185852.

Tired from a day of caving...


Ralf and I went to Torhola on Sunday to draw a map. We made some progress in that, but oh boy, there are so many problems, question marks, and on top of that, it is a lot of work in cold damp place!

It was fun to be in Torhola for an entire day though, with a steady stream of tourists coming to visit the cave. Oddly, most of them turned around at the cave entrance, no flash light, seems too difficult. And two odd guys with helmets and weird equipment! Even if we tried to say you can visit, gave them lamps, explained the cave, and gave some even a bit of tour. The small kids were the most interested in hearing about the cave and most daring to explore though.

The problems had to do with the fact that I had not calibrated my cave measurement device before, and trying to do it before this trip, I run into problems. Not sure if my technique is wrong somehow, or if the device has an issue. After calibration it claims decent accuracy, but the size of compass error is 10x what it should be. Maybe I made a mistake in assembling the device, forging a metal screw somewhere, or bent the mother board, or something?

It is also surprisingly difficult to use the modern smartphone-based software applications for caving. A big part of the problem is that I have no experience in using them, and without someone showing the proper technique by hand, the manuals are not really explaining how to do some of the things I wanted to do. For instance, it is difficult to correct information that the application determined based on measurements, such as what type of a measure a particular data point is. The flow in the applications is easiest when surveying long continues tunnels, but not at all intuitive when the cave branches in many directions all the time.

More about the map later.

Killinmäki Bunker


There's just a little bit of warning tape, but most of it is gone. And one danger sign in a tree, visible from one direction only. The bunker is gone though, or hiding underground, with no easy way to enter. Just some holes in the ground that one needs to be careful of not stepping into.

We visited the bunker in Killinmäki based again on the parenteesi maps from Lynx, and the same Gillobackaträsk map that we used couple of days ago as well.

But this time there was not much to see, the bunker is destroyed, buried, and only these odd holes leading down to the ground remain to cause a danger for the occasional walker. The place is also near an area of houses, hopefully the kids do not play here.

The place is up the hill from the intersection of Vanha rantatie and Kvisintie in Jorvas, Kirkkonummi. Coordinates: N 60.131213 E 24.485167. Again, this is a dangerous place, do not visit if you do not know how to be safe.

Degerby ZIF-25


Googling for more information about the Kirkkonummi bunkers, I found out more bunkers, obviously. But also a tidbit that there maybe 250-300 bunkers in the Kirkkonummi area.

On Saturday Janne and I visited a "touristy" bunker in Degerby, Inkoo. This bunker was of the type ZIF-25, with again one round door. The bunker is probably similar to the one we saw in Masala earlier. That is, one made to house a 100 mm gun. The bunker type is large, with two floors, several rooms, and usually at least two exit tunnels.

This particular bunker is very easy to reach, next to the road at Inkoon Rannikkotie 551, Degerby (N 60.078693 E 24.144999). There's an easy parking spot on the grass, the round gun door is the way to enter, and there's a wooden platform to stand on inside. On the right side there's even a light switch!

(Of course, we didn't stay on platform but explored a bit further in this totally blown up piece of concrete blocks and twisted rebar. On the safe part, half of the bunker seemed too dangerous to enter. Still, there's too much rebar even on the other side, be careful out there if you make a visit.)

The Degerby pages and the Porkkalan Parenteesi pages have a bit more information.

Jorvas Bunkers


How can one work somewhere for 25 years, and NEVER visit a lake just a few hundred meters away? I really don't know, but in my defence I went there today. And found trenches and flooded bunkers.

Kirkkonummi underground is the theme of the month, apparently.

Next to my office there's a lake, Gillobackaträsk. A forgotten lake, between a rarely visited cliff and the highway. Per the orienteering club's map of Russian occupation-time remains, there was supposed to be a trench, three dugouts, and two bunkers on the lake's southern shore.

We set out to find them with Jarmo. By the way, I'm so thankful that he joins many of my adventures, be they underground or on skis. Thank you! But for some reason none of my colleagues wanted to join the wonderful walk to the muddy forest in pouring rain, in the darkening evening. Very odd.

Anyhow, we found more possible dugouts than the map indicated (though we can't be sure if all have been made by Russians, or are really dugouts). We found the zig-zagging trench, now more like a ditch, and a very interesting bunker. Despite searching for half an hour on the right spot, we did not manage to find the other bunker though. Strange. Clearly we were on the right spot, because there were excess stones dumped nearby.

But the bunkers can be very hard to see, so was the bunker we actually did find. And once again, there was a hole in the bunker that one could attempt to enter. Or even walk into it by merely wondering in the forest, if one were not careful enough. 

The entrance had a few of the rebar steps still usable, so I climbed to the bottom. The bottom was filled with water, but I had tested that it wasn't too deep for my boots. At the bottom the rest of the bunker continued through a corridor. However, the water deepened immediately after the entrance, to maybe a meter and half deep, leaving only a few tens of centimetres of air on top. We would have needed wetsuits to continue, and would have had to wade in the water without knowing what ammunition or other dangers lay underneath.

So I came up, and we continued the tour. But this bunker was definitely interesting, and worth visiting. Glad I could snap a few pictures from the inside.

Coordinates:

Update: Doh, per the video that Jarmo found later, we missed an entrance to the bunker. Obviously, bunkers will have at least two entrances! It also seems that the bunker can be dry at times. In October 2017 during our visit, southern Finland has received exceptional rainfall. 

Warning: be careful in visiting any of these structures. Bunkers can be particularly dangerous.

Book on Espoo's Nature Sights


Got the "Kotinurkilta kallioille -- Espoon luontokohteet" book today in mail. Very interesting, can't wait to go through this book, and what treasures it will reveal!

The book is edited by Jussi Helimäki and produced by the city of Espoo. Buy it from AdLibris.

Russian Bunkers in Masala


Is that a green mushroom, or is somebody trying to exit a forgotten and blown-up bunker? Jarmo and Eino joined today for a walk through Masala, in an effort to again find bunkers left from the Russian occupation of Kirkkonummi. We found three bunkers, one of which was very interesting. Even if dangerous.

The map from local orienteering club, Lynx, was once again useful: map of Ingvalsby. Maps of other areas can be found here.

We found the remains of two bunkers and one bunker/warehouse. The first bunker was a tiny closet. Not clear if there had been something more here at some point. Coordinates: N 60.15385901 E 24.52339043.

The warehouse was well preserved, but easy enough to enter so that there was plenty of junk inside. An interesting building though. Coordinates: N 60.15336494 E 24.52304893.

The rainy walk towards the third structure turned into a very wet one as we had to cross small rivers and a swamp area

But the third discovery was both amazing and scary. This was a full size multi-story bunker with several rooms, covering a large area, and a large round main entrance door that had been filled with concrete. And the whole bunker had been destroyed with explosives, perhaps by the Russians as they left.

Still, there were two holes to enter the structure. However, inside the floor slabs were tilted in different directions, boulders and pieces of concrete about to slide down, walls made of broken pieces of concrete held together only by the rusted pieces of rebar. 

We decide to peek inside, and I went through from one of the entrances to another one. But we did to dare venture to the lower level, as climbing back would have forced us to climb a wall of rebar mesh with concrete pieces hanging from it. And we could not enter the other rooms than the entrance hallway, because on the second floor the blown-up floors were merely loose collection of hanging pieces of concrete. I think it is possible to to tour the whole bunker, just that we felt it was too dangerous.

Coordinates of the blown-up bunker: N 60.156343 E 24.509429.

Update: it seems that the round opening is for a gun, similar to other bunkers in the area. I learned more from this link.

Warning: kids, do *not* enter these bunkers. Underground, destroyed structures are dangerous and could collapse at any moment. Actually, this applies to adults as well. Stay out. Also, the whole area is dangerous, because the few holes into the bunker have been grown over by grass, so it is possible to fall into the bunker just by walking around.

Greetings from Neuhintertux


I've been a couple times at the Hotel Neuhintertux in Austria. A wonderful place, great saunas, very nice views from the top floor pool department, and very friendly staff. And, of course, next to one of the two around the year open ski areas in Europe.

The hotel keeps sending me greetings for Christmas, but now I also got a birthday greetings card. Nice!

Silo 468


One of the large, round oil silos in Helsinki's Laajasalo has been decommissioned, and turned into a light show. Nice!

There was a surprisingly large number of people visiting this late on a Saturday night. A sausage grill shack had been set up near the parking lot, in traditional Finnish style. Janne and I walked past it though, and ended up in eating a very nice meal in Laajasalo, at the Spanish restaurant Del Mar.

Sundsberg Bunker


I've been resting my feet last couple of days, after some treatment by doctors. But today I felt the urge for at least a small visit, somewhere. Maybe an abandoned bunker from the Russian occupation times?

The expected position of the bunker was only 500 meters from the parking lot, but I also had to drive, and I'm not sure if my feet likes the pedal pressing and everything else that goes along with starting to move around. But they seem to be OK... mostly. Lets see. Definitely better than last week, and much better than a month ago. Hurting a bit after the day's walks though.

A large area of Kirkkonummi was occupied by Russians after the World War II. The areas were given back 1956. For the most part, you cannot see the remains of the occupation in daily life, but if you look hard, you will find plenty. I got a tip from my friend Merja about good maps for the remains of the occupation, maintained by the local orienteering club.

The bunker was not easy to find though. There's a few depressions where the trenches have been, but I walked by the bunker without noticing when coming to the area. After a more careful search, I found an area with a half-buried entrance door in a pit, and several well-type holes in the ground. The whole area looked like the bunker would be no more.

But to my surprise you can actually enter through the door, walk down a couple of meters, and most of the underground part of the bunker is still there. There's the sloped entrance tunnel, an almost intact small room to the left, a corridor to the right with a blocked exit towards the roof, and a big mostly collapsed room. But you could probably crawl from the collapsed room to the one of the "wells" -- probably a gun mountain point.

Coordinates: N 60.16168609  E 24.56914241.
