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.

The Inkoo Superbunker
There's a big contrast between warm summer evening in the countryside, and what you find a few meters under your feet: a massive, blown up Soviet-era bunker. Damp darkness, rebar that is difficult to crawl through. And we're here to practice photography!

Something in the darkness...
Saw something in the darkness on the walk back... is it a bouncy castle or a space station? Nah, turned to be just another data center. #Kista

Is it an aquarium or a construct of the evil nazi regime? Well, both...

Recycled Hamburg flak towers
During World War II, the Nazis built so called Flak Towers -- fortified air defence bunkers -- in three cities, Berlin, Vienna, and Hamburg. I had previously been in the Thumboldthain tower in Berlin. Now I was able to visit two similar bunkers in Hamburg.

The Secret Keyhole
What a find! A secret garden, but with a keyhole that reveals the most beautiful view onto it, with St. Peter's Basilica exactly in the centre of the view.

Cestius Pyramid
I did not realise there was a pyramid in Rome. Not huge, but still impressive Cestius Pyramid! Modelled after Egyptian or other pyramids, perhaps

Pihlajasaari Bunker
Helsinki's recreation islands are interesting, also from the point of view abandoned military structures and ruins. Today's excursion was to Sirpalesaari.

What's This?
Mystery metal hut. I was looking for an entrance to a tunnel I saw in Rotebro, but was in the end unable to find a way in. I did, however, find an odd, round metal hut at the top of the cliffs.

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.
