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.

Walls of Piran
Piran is a medieval town on the coast of Slovenia. A wonderful town, clearly retaining its historic parts. The protective walls of the city date back to the 7th century, and can be toured for a nominal fee. Much recommended.

Northern Croatia swim
On our tour of Slovenia's Piran, we also peeked on the Croatian side, and had a swim in the Polynesia Beach in the town of Umag. Little did we know that the ruins we started our swim from were actually the ruins of the Sipar Castle from A.D. 1000 or thereabouts. Some have even called this place the Atlantis of Sipar. Interesting!

One kilometer walkway tunnel
This tunnel appeared on my walk while visiting Rotterdam. I was walking from my hotel to the conference venues, as a like to do to keep my step counts up :-) And as one expects, there are some waterways to cross in the Netherlands cities :-) I thought there'd be a bridge though. But no, it was a tunnel. It was only in the tunnel and later in Wikipedia that Maastunnel is actually 1070 meters long that crosses the Niewwe Maas.

The Golden Gate of Sääksmäki
We visited an old, not so big, but quite famous bridge in Finland. This used to be on the main road, but since the opening of the highway from Helsinki to Tampere, it is no longer getting as much traffic as before. The bridge is still beautiful, though.

Trust me, it is NOT a watertower
It does look very weird. For some reason I thought it was a water tower. It is in the town of Oberreid in the Black Forest area in Southern Germany, near Freiburg. But ... it is in fact a defense against against nuclear weapons and natural disasters...

Kalemegdan bunker
In the Kalemegdan park / Belgrade Fortress there's also a bunker. This is a bunker Tito ordered to be built, and it was constructed in early 1950s. It has two gun ports (now closed), and it is today an open museum that you can visit.

Dockyard Garden
Dockyard Garden is an old dry dock in the Yokohama harbor, cornered between some of the highest skyscrapers in Japan. Doors have been cut to the sides of the massive rock walls protecting the dock, to build access to nice restaurants at the bottom.

Enoshima Caves
Only in Japan: They have a "candle lending service" at cave. And it is not like it is a dark, lightless place even without the candles - the Enoshima cave has lighting, but obviously the candles are a remarkable addition to the experience. On the other hand, since the candles are actual candles with actual fire, there is now a need to have a fire alarm system, if somebody accidentally sets the cave on fire...

New ZIF-25 bunker in Siuntio!
We had heard a rumor of a potentially previously unknown bunker in Siuntio. Let's call it the Hoivakodin Bunkkeri (Retirement Home Bunker). It turned out to be accessible -- if you don't mind passing through pieces of concrete hanging by rusting, twisted rebar. And it was a massive one! Another ZIF-25 model bunker, i.e., a two-floor bunker with several entrance tunnels and a side mountain gun port.

Slava Ukraini!
I saw something today that I didn't realize actually existed in our neighborhood. It takes maybe half an hour for me to get from where I live to Siuntio, and there's a nice castle, the Sjundby Castle (or Manor). It was built starting from 1417, by the rapids on the Sjundbyån river. It is not open to the public so maybe that explains why I haven't heard about it.

Wiesliczka Salt Mines
Wiesliczka is a suburb of Krakow. Under it is a massive salt mine, extending to a depth of approximately over 300 meters, with the total length of labyrinth passages spanning over 287 kilometers. The use of the site dates back to the 13th century, where the locals would harvest salt from brine (salt concentrate) wells dug on the wetlands. Later in the same century the wells started to be extended as deeper mine shafts and tunnels. Wiesliczka is not just a mine, it is a massive underground world and site of art and history. It is also a well-deserved UNESCO World Heritage Site.

Communism is closed, so is the museum
We went to the Krakow Museum of Communistic Poland... it wasn't open, and neither is communism. Would have been very interesting to tour this, but oh well.

Refresher course in communism and nuclear bunkers
I've been here before, but a refresher course is always good, plus I have the next generation with me, useful course for him as well. The Prague's communism and nuclear bunker tour is a good reminder of what oppressive things went on during the eastern block years in Czechosloakia and elsewhere. Fortunately, those times are past us. But in 2022, you can still feel the nuclear-bomb threats being made ... you guessed it, from the east.

Castles, castles... Czech edition
I had an opportunity to visit castles in Czech Republic this summer. The first one we went to was Hrad Trosky, the ruins of an amazing two-tower steep clifftop castle. What a magnificent, for defense business -only castle! The second castle, Hrad Kost was a more full-service one, and was used as an administrative base. With a torture chamber, of course. (Is there any other kind of administration???)
