Stp. Graf Spee and Stp Westlich den Haan
1. Marine-Funkmessabteiling Headquarters
De Haan-Belgium

Updated March 19 2007, July 9, July 16 2007

All pictures are (c) 2006 T. Cools exept for the Black and white pictures and some colour pictures which are (c) 2006 Marc Doigny.
Two other black and white pictures are (c) 2006 Zeepreventorium, Public Relations, André Viaene, this will be mentioned seperately.

I would like to thank two people who helped me with locationg the bunkers:

Marc Doigny who's home page is situated here:  http://zeepreventorium.org/
Erik Viaene for using some of his picture archive and maps:
Copywrited pictures and plans from Marc Doigny and André Viaene published with autorisation.
Also with special thanks to Dirk Peeters for feedback and WWII Air Picture.(with waypoints and tracks)

From September 1941-May 1944 a radar site was situated along the coast of the city De Haan in Belgium.  During that period it was commanded by Kaptain W. Hahndorff.  From 1944 the headquarters were moved to Gent.  The radar site also served as an instruction school.  At first sight only some flak bunkers are left but there are still some bunkers situated at the Zeepreventorium hidden under the sand dunes or beeing used by the preventorium.  One bunker has been demolished in 2003.  Many others have been blown up during the seventies and eighties mainly those in the sand dunes.  It is believed that all remaining bunkers are now protected by the Zeepreventorium.

Three bunkers were investigated and entered on a bunker fieldtrip research of March 18 2007.
The bunker at 'De Kijkuit' seems to be a 502, just as the one near the tunnel to the beach.
Another watertank bunker has been unveiled beeing a 195.

The following types of FuMO(Funkmess-Ortung) active radars were situated here:

 1x FuMO 214 Würzburg-Riese
1 x FuMO 3 Boulogne
1 x FuMO 2 Calais B
1 x FuMO 213

And FuMG(Funkmess-Geräte)

1 x FuMG 40 Kurmark

A bit of history of latest events:

Recent research and visits revealed some very interesting discoveries at Stp Graf Spee.
Although some bunkers still have to be identified definately, the discovery of a 198 Wasservorratsstand 60cbm was a big surprise.
Although others like this have been build(Vlissingen), they were rare and all others are probably gone.
Another small non standard bunker with standard 'Trinkwasser' watertank was discovered.  The metal tank was still in place and the bunkers were recently re-discovered and investigated for the first time in more than sixty years.

We succeeded in continuing our investigation and found another two 502's and one 195 on 'Bunkerday' March 18 2007.  We did our investigation that day in extreme weather conditions with the wind blasting at 9 beaufort !. The day began with streaming rain but later on we had a sunny 'windy' afternoon...

On June 17 2007 we went on with trying to dig through the entrances of the 2(...) remaining bunkers.  We didn't succeed in digging through the soil of number 12 so we abandonned this one and went on with trying to uncover number 13.  Unfortunately something went wrong and almost ended in disaster...  See further.

Green colours mean they still exist.
Red colours mean gone or disappeared under sand.

Plan of the location of the Zeepreventorium.  It was also given to me be André Viane but this one's  from Marc Doigny.
It shows the location of the different buildings and bunkers.  The markings and colouring are made by Marc Doigny.
The original plan can be found here:http://zeepreventorium.org/index.htm

Bunker numbering

NGI-plan=Preventorium-plan

1:198: Wasservorratsstand 60 m2.
2=7: Small non-standard Watertank bunker.
3=4: 502:Doppelgruppenunterstand.
4=3: Flakbunker.
5: Bunker in the dunes which resembles a gun position with some brick structures.
6:Bunker in brick mostly hidden in the dunes.
7=5: Flakbunker
8=6:195 Wasserversorgungsstand 25 m2.
9: Bunker beneath 'Ellegria' Bunker not yet defined.
10=6=502: Doppelgruppenunterstand.
11: Antenna Position in dune pit(gone).
12: 'Kabelbaanbunker' still there but unexplored.
13=2=502: Number not yet on plan but north of number 11.  We almost had a fatal accident there.

At the 'Kijkuit'  2 bunkers wich were found on air pictures are still unexplorered after bunkerday March 18, 2007..  Investigations later on are indicating they are probably gone.  Another bunker some 100m to the  southwestside of bunker number 8 is also unexplored as number 9 under 'Allegria' and number 12 is still covered by hard sand and rubble.

NGI plan with the GPS locations track of our fieldtrip of January 7 2007.  Measured with a Garmin GPSmap 60CSx.
All numbering of the pictures below are referring to the NGI map.  Number 13 isn't there but located north of number 11.

Track and waypoint projection on a Air Photograph of our fieldtrip of January 7 2007.
The numbers corresponds with the NGI plan.  Click to enlarge.

Most probably an Air Photograph taken in the fifties with the fieldtrip 2007 projected on it.

 And in Google Earth with a WWII reconnaissance picture overlay. See further for more overlays with different angles.

Digging began.

_

_

Metal flap of the tank.  It has been put back into place after photographing it.

Camouflage still visible !  I had some trouble with humidity and my flashlight.

Bunker 1; Type 198: Wasservorratsstand 60cbm

Fieldrip identification on January 7, 2007

First entrance in more than 30 years !  A discovery was made, This is probably the only 198 left over on the Atlantic Wall !
The tobruk which was installed at the right side of the bunkers couldn't be investigated.  It was used by the Zeepreventorium as an oven during the seventies and eighties.

198.  Plan © Rudi Rolf(www.rudirolf.name)

Some weeks earlier...

_

Threatened by builddozers, a nightmare for bunker enthousiasts.  Fortunately not for this 198.

_

_

Right: Preventorium picture with the 198 in the foreground.  The bunker was beeing used as an oven(Tobruk).
Two other bunkers in the background are also visible.
Left: Situation now.

Tobruk location: used as an oven, the chimney is gone.

Entrance.

Right: Room 1: 'Gasschleuse', behind that room the 'Brunnenraum'.

_

Oxidised filters.

Left: Pump room or 'Brunnenraum 25'  At the end the 'Notausgang' but it was sealed off.
Right: View on one of the water tanks 'Brunnenraum' 24.  This is the outer left water tank room.

Bunker 3

502 Plan ©Rudi Rolf(www.rudirolf.name)

This is only the entrance leading to the bunker.  Revealed on 'Bunkerday' March 18 2007 as a 502. Situation January 25 2004.

One of the entrances  found !

The place to go through...not without danger however...

_

Left side entrance: Code OST O   ....... 4

'Eingang' to left to 'Bereitschaftsraum 3(L)'

_

_

_

Again very vague code number on the right most entrance.

Bunker 4: 2cm Flak with ammunition depot.

_

Situation of the flak position in January 25 2004.

Small annex for Ammunition.

Bunker 3 and 4 together from a cropped photograph from the air.
The first one clearly showing the entrance design.  Bunkerday of March 18 2007 revealed it to be a 502.  The entrance however is special. The two entrances are at the left side with in front of it a protecting wall.

Roof: Look at the Beach Boys inscription !

Bunker 7
Same 2cm Flak but without ammonution shelter.

January 25, 2004.

_

_

Inside, graffity all over.  Now it is even worse.

_

Left, footprints.
Right Flak gun emplacement.

This bunker has been used as a museum for the Preventorium.  Nothing Atlantic Wall related however.

No number

_

Position of the Vf bunker now probably gone.  This is a comparison picture.

Air picture of the Vf, not far away from B3.

Bunker  8: 195 Wasserversorgungsstand 25 m2

_

Type 195 revealed on Bunkerday March 18 2007.  A Wasserversorgungsstand 25 m2.

_

Right: Cropped image showing the same bunker.  It had also a chimny build upon its tobruk which was used as an oven.

_

No much luck with finding the entrance, thinking it is a 502...

Wasserversorgungsstand 25 m2, Type 195.

Plan: ©Rudi Rolf(www.rudirolf.name)

This type and the 198 are only to be found in AOK15 and was forbidden to be build from July 27 1943 on.
So this would mean they are from an earlier period.  They were replaced by  a R646, R658 or R659.

_

Entrance with vieuw on 1, Gasschleuse.

_

_

Vieuw on two of the three 'Wasserbehälter', 24 rooms.

_

Room 81, Lager und Notabort.

Two bunkers visible: the one to the left is still there but completely under sand(number 13-not on NGI map).  Bunker 8 to the right.
The one on the left is still existing and we tried to uncover it on June 17 2007.

Here's a report of the events of June 17 2007.

Bunker 13: 502

_

Look at the black and white picture above: the bunker on the left is the one we are digging up, this is the beginning.

_

All went well untill one of us tried to enter the bunker and the sandy ground collapsed covering the one who was trying to enter.  We couldn't do anything and phoned for help to the fire brigade and the emergency services.  Fortunately the guy managed to enter and while we were trying to uncover the entrance he was taking pictures inside...  (I hope to publish some of them)

_

Just after we liberated him, all was well but no one entered this one again.  We learned a lesson that day and this is that you may NEVER do this alone and be VERY, VERY carefull by knowing what you are doing.  This is a very interesting and learnfull hobby but can be very dangerous.

The bunker was covered with sand again and we went home happy nevertheless.

Bunker 9

_

The Allergia, build upon a bunker.  Only part of the roof is visible.

_

Left: Part of the roof.  Right: at the backside there's some kind of entrance to a tunnel.

_

Tunnel ?   Right: Periscope or chimney ?

Bunker 10: 502

_

Revealed on Bunkerday March 18 2007 as a 502.  Worth investigating !

_

Left: the bunker in the sixties and at the right the tunnel as it is now.  The tunnel was build around 1924.

_

__

Digging began on this bunker around 10 o'clock on March 18 2007.  We found the one of the entrances some 4 hours later.

Video click here:  http://video.google.com/videoplay?docid=4089751919117771106

_

Bunker code number Ost-O 09-29.

_

_

_

Bunker 5

I found this on a personal trip along the dunes of De Haan on March 6 2006.

_

An open gun emplacement ?

_

Closer look.  There's a cave in front of the left picture, probably hiding something else.
This is close to the place were the Würzburg-Riese radar stood.

_

Bunker 6 above: I also found this brick structure on March 6 2006.
It is probably the one in the center right picture.

Different angles with Google Earth Overlays

_

There were two anti tank v-shaped walls on the left picture.(click to enlarge)

Below the bunker on the beach.  It is gone now. A677 or 612 ?


 

5 and 6 are referring to the bunker numbers at the beginning of this page.

The two identical structures in the dunes haven't been  identified yet.

Not far away from the Zeepreventorium there is a small Vf construction but probably not related to Stp Graf Spee.
