EXPLORING A WW2 BUNKER and Opening the 'SECRET DOOR' hidden in the Floor. Mystery Finally Solved!

Drainage, but i tought it would be deeper...

[@eileencarroll6418]

In the US it is called a dry well; in the UK it is called a soakaway. Purpose is to temporarily hold rainwater and let it slowly dissipate into the ground. In the US, they are usually underground chambers filled with gravel so the rainwater moved around the gravel. Yours seems to have staggered bricks to create temporary space for water to move through. It seems to have worked.

[@BUSHCRAFTTOOLS]

Great explanation. Thanks for commenting

[@bbranett2188]

[@brianbenninghoff3394]

[@garyo4057]

[@simonwilliams1740]

100% soakaway drainage, obviously not a high water table hence the dryness and the lack of proper drainage.

[@bubbablanding6084]

As a former air defense artillery officer who served in Europe I am pretty certain that these are ammo bunkers in an area where large antiaircraft guns were emplaced. Guns were emplaced on concrete pads similar to the one he commented on as he walked between bunkers. The bunkers probably served two or three guns each. He commented that these were close to an airfield, and airfields were always heavily defended by large and medium anti aircraft emplacements.

[@FullNelson007]

I was thinking the same thing. Some type of ammo storage

Dustin here in the states we call that a sump hole. As water sheds down the stairs of the bunker there needs to be a place for it to absorb it back into the earth instead of flooding the bunker.

[@monkeyboy6590]

The hole has two purposes. 1. Water drainage. 2. Grenade drop. In the military, anytime we build fighting holes or air raid shelters, we always equip them with a place for water to travel to and if we are attacked by ground troops, and a grenade is thrown into the entrance, the grenade would drop in and protect the occupants from shrapnel.

[@tommywolfe2706]

I would have never thought of a grenade drop....I know that bigger bunkers have bends and walls with holes for engaging intruders, but that makes total sense consider the size of these bunkers. One grenade makes it in that hole an the whole entry would get smashed though....lol. I suppose that the air vent is both an air vent and emergency exit in that case?

[@larrydriemel6242]

why would you put a steel cover on a grenade pit? a grenade won't give you enough time to take the lid off, you could just close the door,or stand to the side,. some people get confused by the obvious :)

[@goldenmath4091]

We found holes like this as kids, we lived on the outskirts of a WW2 airfield, the holes went down and opened up into war rooms , they will filled in over time by the council as we're dangerous, we found many shelters, tunnels etc it was great fun as a kid, and this takes me back

[@jamesellsworth9673]

Closure! A bit of a cleanup, ventilator caps on the top openings; rebuild the loo on the bare above-ground concrete slab...and you have a start on a homeless village.

[@jjudy5869]

A standard manhole in the US is 11" x 16". If it was an opening for tunnels between bunkers I would assume it would be that size. So I would say everyone's summation that it is drainage and the fact the floors are dry and the walls are not rusty would be a good guess as well as the lose brickwork. Never heard of a Grenade drop but it makes sense as described.

It's a French Drain, it's probably a 6' hole filled with gravel, to allow the rain water to slowly drain into the ground.

[@Bear-kr3gr]

It’s a French drain. A pit of gravel at the bottom of the stairs to allow rain to drain away and not fill the bunker. In the states if you have a basement with no exposed walls but a stair down to it outside you’ll have one of those. Old old old tech and doesn’t work in wet ground conditions cause the gravel pit fills up with water and overflows.

[@peterforden5917]

When I was a kid (I'm 70+ now) my dad was in thde RAF, and I used to play in the air-raid shelters around the various stations, but played in them the nea by the 60's most had been destroyed because of the dangers to kids like me! both boys and girls,the girls tended to take over the one nearest the amq (airmens married quaters)and play games like "HOUSE" etc, they were usually cleaner and drier!,, we boys plaed in all of the others MOSTLY abandoned , those that werent were FILLED with axe shats different types of axe head an pich head an thousands og military pocket knives, we never touched them because if caught by the RAFP t(snowdrops!) they'd inform our fathers through official channels and we'd get a walloping for the black mark on THEIR records. the shelter looks like a prewar/early war shelter due to the "quality" of the entry way not just a few huge concrete slabs with only the door way being brick work their were some ar former RAF (NOW ARMY AVIATION SQUADRON) TERN HILL in the square in front of the old AMQ (not BUNTINGSDALE ESTATE which was bui being nuilt from around the imd 50s and and finished byc58.,) there being shallow bomb shelter at each corner (probably more shrapnel proof designs) they'd all gone when I was there last in 1999, which was GOOD maybe not for the archeology interested, but I remember near drowning in the one nearest to my hoUse,I was abut 3 at the time and my Mum made me sit at the bottom of the stars as a punishment!. If I were you I would check your Map and find out what was near by ie an ammo dump airmens or air womens quaters cookhouse etc they wouldnt have been in a semi circle fior nothibg , really enjoyable! brought back several forgottten memories, Thank you. keep it up :)

[@jackieow]

As of 1940, Churchill knew Operation Sea Lion could be activated at any time, and Britain could be totally overrun by German forces. Against that contingency, he wanted forests around as many villages as possible inhabited by Resistance forces that could harass the occupying Germans. They were to be assembled in groups of about half a dozen men, handpicked by mayors and police chiefs who would have a clue who was upright and dependable, and could be capable of handling weapons. These men were to be housed in quickie small bunkers scattered around the forest, such as shown in the video. Unfortunately rifles were in such short supply that each group could only be given one .22 caliber rifle, as the more powerful rifles were needed on the battlefield. The job of these men in groups of half a dozen was to sneak around as best they could, sniping at the heads of Nazi soldiers on patrol, knifing sentries, sabotaging German ammo dumps, etc. etc. They knew that upon invasion, they were to assemble in their respective group locations that were pre-built (as shown in the video) and pre-designated for each Resistance group. The commander of each location had a prime initial directive: unlock a top drawer and carry out the command sealed in the envelope. The command for each Resistance group was: to kill the local mayor and local police chief. Churchill knew they would be tortured, and have family members tortured, to force them to talk and reveal the identities and locations of the Resistance group members they had named. So, Churchill knew that owing to the exigencies of war the only way to reliably break the chain of knowledge about the groups and their locations (lest members have their families tortured to death to try to blackmail surrenders) was to kill off the officials who had made the selections in the first place. Of course the covered pits in front of each location were to drain away pulses of rain water. At the same time, Britain was appealing to ordinary U.S. citzens, from the Embassy in Washington D.C., to contribute personal firearms from all across the 48 states. They were literally mailed in by thousands of individual U.S. citizens and sent from the British Embassy in Washington D.C. to London, for distribution toward immediate combat needs. Also at the same time, American Army Air Corps commanders were with a wink and a nod instructing pilots to accidentally land their warplanes in southern Canada and forget where they had parked them, so that Canadians could repaint U.S. warplanes with R.A.F. insignia and fly them for use in England's blitz predicament. America had to put some of our own military people on assassination lists as well, in that U.S. soldiers who were technically trained (e.g. radar and some radio equipment) were assigned the "protection" of personal "bodyguards." Actually, the bodyguards were there to murder the technically trained U.S. servicemen on the battlefield any time their positions were about to be overrun. Churchill did not want English officials being able to talk about Resistance fighter identities, and Roosevelt did not want certain types of technical knowledge to fall into enemy hands either. In a similar albeit less serious vein, as soon as the U.K. declared war on Germany in September 1939, everybody knew what that meant because World War I had been such a recent experience in living memory. There had been a protracted and lamentable lead up to Hitler's invasion of Poland, with the sequelae being obvious to those who knew history was going to be repeated but in a more terrible way with weapons of increased severity. Thus, the day after England went to war almost everyone killed their pet dogs and cats. They knew there would be too little time and money and food to go around as it was for just the humans.

Awesome comment. I thoroughly enjoyed reading it.

[@tm5aw357]

[@piddy3825]

Yeah, drainage. I doubt the bunkers would have been connected by tunnels considering the size of the openings. much to small for any practical purpose of moving people or supplies, but perfect for allowing adequate water drainage. If you really wanted to make certain, I guess you could go and open all the remaining intact covers and excavate the one with the debris in it. but I do think you satisfied our curiosity. Thanks!

[@MrVinz377]

Imagine having one of those bunkers in the back of your own garden , would be cool...just in case things go bad ...

[@Familyman0838]

These were built as air raid shelters not to protect against ground attack usually situated near air bases or artillary emplacements the larger of them looks like a ammo store or for fuel etc

[@hogfry]

A tunnel entrance would be INSIDE the bunker behind the protection of the door. Since its at the bottom of the stairs it's probably a drainage cistern to keep water out of the bunker itself. Usually those have an aggregate in them to allow water to drain away but stop debris from filling the hole. Large stones or brick sometimes chunks of crushed concrete... Etc.

[@finncarlbomholtsrensen1188]

In Denmark the Germans built a lot of bunkers on our West Coast to prevent an English attack, and some years ago one was found to be untouched, since the war, when being left by the German troops. They managed also to make a contact a soldier who had been there, from the papers found, and today the actual content has been moved to a smaller Museum in a local town nearby. Still to be seen.

The sole function of these WW2 buildings was as an air raid shelter. ...... As many have stated, the hole looks like a soakaway, and probably is, although the concrete lid is resistant to water, as the sides and hole would soon become jammed with dirt. ...... That said, these bunkers would resist all but a direct hit, and were a good investment.

Yep a drainage sump. Or. Someone had already taken the treasure and filled the hole. 😉 They could have been munitions storage, as they’re not far enough underground for bomb protection and they are far apart in case of one exploding. The same sort of thing is in western Queensland, but are much bigger and are now used for tourist accommodation! There is a related museum on site as well. Very quiet stay. 😁

[@ianddavidson1]

Air raid Shelters. These are very typical Stanton shelters. Assembled from pre cast concrete sections bolted together at the top, and with brick built ends. Sizes vary, based on the number of sections used. Stanton shelters can be found used as civilian shelters (There are two extant in West Bridgford, Nottingham), and they are very common on WW2 era RAF airfields, particularly on the dispersed sites. The concrete bases are for huts, which were often timber, or plywood with tarred-felt on the roofs and walls. These have either rotted over time, or were dismantled and "re-purposed" at the end of the war.

Those bunkers have open skylights, which would detract from their efficiency as bomb shelters. As they were near a wartime airfield, it's more likely that they were ammunition stores, and the top openings were for winching up (or down) ammunition for the nearby anti-aircraft guns.

[@bikerleo1966]

[@frederickgassmann]

Sump drain for water drainage. Gravel and empty spaces built in to allow water to drain out of the open entrance way back into the soil.

[@leuvenlife]

metal was scarce during wartime, drain holes were often made of concrete.

[@curthill7123]

I think it is a simple sump drainage. Likely the entire structure sits on large sump with coarse fill. The drain you found allows the water to filter into the surrounding drainage field. They may have individual drainege fields, or one very large one.
