Pantzersstützpunkt Ostende Hafen
Halve Maan

Updated January 23 2005, January 4 2016(with pictures from 2009, 2012, March 24, 2013)

Revamping this page at the moment.

During WWI this location was used as the German Battery 'Eylau'.
During february 1943 the Hundius battery was constructed at the same place but was moved later on in the direction of 'Fort Napoleon'.

These constructions are still visible:

- R610
-R515(with one only entrance, possibly 3 or 4, according to some sources  were build)

Further at the lockhouse:

-Machine bunker(Fishing museum)

No confirmation about these:

The location of the individual emplacements have been measured with a GPS Garmin Etrex Legend.
The position of these emplacements are projected on a NGI(Nationaal Geografisch Instituut) chart which has been extracted from a NGI CD ROM.

The 3 flak emplacements of the Halve Maan battery.  Right the brick building on position number 14.


R633 Bunker for M19(Machinengranatwerfer).  Number 3 on plan.  Ground Plan with numbers assigned by Rudi Rolf.
This R633 is the only one remaining at the Belgian coast.
As an extra feauture, there's a Tobruk installed at the right side of the bunker.
You better ask permission at the lockhouse to enter this bunker and the Vf buker below !

Emergency exit 'Bereitshaftsraum' number 3.


Stand für M19.  Number 42 on plan.  With text in it.

Vf bunker one room and a corridor.  Number 2.  Maybe World War 1.

Guardbunker number 4(not visible on plan).  Original Location ?


R656 at location number 7.  Plan an numbers by Rudi Rolf.

Right entrance R656 number 7: Ostende 01-134 V


Text in the R656 number 7: Bereitschaftsraum number 3.

Canteen: number 9.

R610 command bunker: Number 10 on plan.
The interior has been altered in such a way that nothing much is left.
The upper section has been added by the Belgian Marine.

Above and below:
Between the R610 and the R515 are two 7.5cm Polish gun emplacements with their direction markings still visible.  4 were build but only two found.
Those two pictures are taken in 2012.

R515: Number 13 on Plan.


Number 17: Modified L421A command bunker with an open emplacement on top.
Below, same bunker June 13 2012.


Left: 01-132V at entrance.
Right: Number 2 Nahkampfraum.

Top of the L421A.


L410A: Number 20 on plan.  Flak bunker.


Gun Emplacement number 10 and entrance.

Picture taken in the 'Bereitschaftsraum 3' but looking at rooms number 22(L) and 33(R)
Number 22=Lüfterraum
Number 33=Unteroffiziersraum

The numbers on some of the room entrances are probably from the Belgian Navy
when the bunker was in use by them after WWII.

Concrete room used for storage.  It is formed as en L.
In the background you have the light flak emplacement number 22.

Open emplacement for light Flak.  Number 22.

Brick building number 23.


Number 31: R515(MG-Kasematte am Vorderhang/ Casemate for MG with forward apron) incorporated into the dyke around the 'Halve Maan'.   Only the rear section still exists.
I believe that the picture from 1942 is a picture of the same bunker.
The pictures below are from 2009 when renovation works started of the 'Halve Maan'.


Below: The bunker is largely destroyed, only the entrance still exists but the bunker numer is clearly visible:
Ostende-(Hafen) 01/V-115.
