THE URBAN EXPLORER

Welcome to The Urban Explorer blog! We have stories about urban exploration from around the world, from interesting public places to hidden, exploded bunkers with rebar pointing all the wrong ways.

Karby Batteri
More after-work bunker scouting. I thought I had already explored all the underground structures in the northern Korvlinjen, but apparently not. This "batteri" as they called it is a set of defence structures for guns, with small tunnels going from one structure to the next.

Deadly bunker trap
Well, that was dangerous. We're very careful when we visit blown-up bunkers. But, we did not expect intentional traps, at least not recent ones. Next to a bunker in Siuntio, Jarmo almost fell into a 5-meter deep well that was covered with fresh tree branches. Would he have hurt himself if he fell in, or even if not, would he have been able to get out if he was alone? Who does this sort of thing?!

More Sepänkylä Bunkers
Olli and I went to Sepänkylä to visit more bunkers, and to fly our drones. We found a standard Soviet Porkkala bunker model, relatively intact except for the room under the gun hole. But what wonderful flowstone!

Coulée verte René-Dumont
Jeff and I were taking a walk after our meeting in Paris, and happened to run into an "elevated linear park", the Coulée verte René-Dumont. Such a beautiful creation! Also with some old railway tunnels.

Tivoliberget Forts
I had a long day at my Kista office today, but on the way back to the airport I managed to scout ruins of fortifications and bunkers at Tivoliberget in Bergshamra, Solna, near Stockholm.

Petite Ceinture
I'm feeling a bit alone here. The tunnel ends are too far to see even that pinhole of light. I'm in a long railway tunnel on the Petite Ceinture, the "little belt", an abandoned (I think) rail system under Paris.

Juusjärvi Rock Paintings
Last year I bought a book on ancient rock paintings in Finland. There's a painting nearby that is very hard to reach, but with the recent low temperatures, Jarmo and I figure we could cross the lake to go see it.

Skiing in Romania
The winter is running out, and even the HR department though that I had too little vacation. So I decided to take some last-minute cheap flights to Romania to ski in my #57th country.

Stubböle Big Bunker
Another guest blog entry from Jarmo: When I visited Stubböle a few months ago with Jari and Olli we met some local people. They pointed us to a bunker that is not shown in any maps. At that time we did not have time to check it. When Eino wanted to join me on a Sunday adventure in a perfect sunny weather we decided to go and check this bunker.

Will a bunker eventually turn into a cave?
I wonder what happens to human-made underground structures, when enough time passes by? Will they turn into caves. or cave-like environments, eventually?

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).
