Too early for #SubterraneanSaturday - so have an underground #fingerpostFriday instead - a rather steeply angled sign pointing towards Stromboli, deep beneath an volcanic, Icelandic landscape. Includes extra shots for context! August 2016.

For #SubterraneanSaturday - an underground bunker in the old military fort at #Modlin, north of #Warsaw, #Poland.

I didn't have a good source of light with me, beyond an incredibly dim LED flashlight on my phone (this was September 2008) - so was slowly edging my way forward with the autofocus assist flash on my dSLR. After one or two corners - a doorway into utter, empty, cold darkness.

I ... decided to turn around.

@coprolite9000 @KaneG Hey, any chance we might see some more #SubterraneanSaturday pics again? I was quite enjoy that hashtag...

@KaneG
Gorgeous shot!

My own belated contribution to #SubterraneanSaturday - I do so love how old masonry reflects light in tunnels.

(Hopton Tunnel, #Derbyshire - a bit along the Cromford and High Peak Railway from Middleton - yes, there again. Definitely a lot less exploratory than yours - taken in April 2014 while walking the dog!)

#SubterraneanSaturday

Missed yesterday as there were just too many choices, my procrastinating got the better of me.

So, here's the #WellTunnel in the #DetachedBastion at the #WesternHeights #Dover

An area high up on the#WhiteCliffs of Dover famous for it's #Napoleonic #Wartime structures.

Lit from the other end by my best friend, it's one of my personal favourites.

Bit out of the norm as you can actually visit this tunnel complex deep beneath #DoverCastle in #Kent. This is a photo of the #TelephoneExchange in the #CasemateLevel of the #tunnels. Rare to see it without the public tho. 😉

There are actually 5 levels, the staff say there are 4, and 1 hasn't been found.

A - #Annex - done
B - #Bastion - missing?
C - #Casemate - done
D - #DUMPY - done
E - #Esplanade - done (they say it doesn't exist lol.)

Will post more later on. 👍

#SilentSunday

Spent sitting by the Spoil Hole, (where the tunnelled chalk was dumped 80ft onto the beach) at Z Rocket underground shelter Nr. St. Margret's, Kent.

Loong way down and often inhabited by homicidal pigeons who will fly at you in an attempt to make you fall through it.

I said descend on leeeeeeft thud! 😜

Perfect Doug, welcome to #SubterraneanSaturday :)

Anything underground is cool. Especially caves.

Line some up and next Saturday maybe post a few with the hashtag and see if we can find any other people with pics from underground. :)

Wow!

It appears my experiment with a #SubterraneanSaturday went much better than expected. 🙂

I had hoped that a handful of people would be interested in underground photography and exploring, maybe a dozen, but 62 favourite & 43 boosts (and climbing), in less than 24 hrs is incredible. 😎

Hopefully with all the boosts these posts will reach a much wider group of people and more pictures of what's beneath our feet may start appearing. 🤞

Thank you all for your interest. Much appreciated. 👍

Another one just for the lolz, this is an 18"/45cm #NapoleonicSewerPipe that connects the #SouthernCasemate to the #NorthernCasemate in #Dover near the #Citadel, later to become a detention centre for immigrants.

You literally have to have your arms above your head like a diver as you go in, and then scoot forward a few inches at a time with your toes pushing you.

People have said the thought of this size pipe makes them physically sick, I'm not surprised. :)

#SubterraneanSaturday

Here's a shot from deep below #Middleton in #Derbyshire, it's an abandoned #LimestoneMine which can still be made operational if need be.

Where we were is approx. 200ft down, the workings span 25 miles over 3 levels, it's worked on the room and pillar method, with rooms 13 m wide and pillars 17 m square, ceiling height is 8 m.

It is immense, just for scale we have Westy lighting up the tunnel ahead.

@KaneG #SubterraneanSaturday sounds great! I probably won't have anything to contribute to begin with, but happy to follow along and see what turns up...
