The bunker has been inaugurated by Mayor Moenaert on 29 September 2006.  A bomb which was found earlier on December 19 2005 has been put in front of the bunker and is pointing(well, not exactly as I found out) at the previous location of Castle 'Ter Linden'.

Ter Linden was during World War II a German radio measuring station at Sint Michiels Bruges. It was one of the most important radio signal decoding stations in Western Europe used by the Germans.  This German base was located only 3km from the centre of Bruges and was totaly destroyed during two bombing raids of A20's B26's and Typhoon airplanes by the Allies on May 28 1944.
The codename of this bombing raid was 'Operation Ramrod 934'.

During the two bombing raids 19 German Soldiers and 39 Civilians were killed.  1 Civilian was missing and is never found.
Rumours that hundreds of German soldiers and a German General were killed are not true.

Nothing much is left nowadays, the Castle was mostly destroyed and the large bunkers are gone. I only found two 'ringstands' and a small open defence bunker.  The ground in this area is still filled with unexploded bombs.  Many houses have been build above them but they are protected by a concrete plate.  Still, during ground works, in December 2005, a bomb was found and had to be dismantled.

The two 'Adcock' basements are probably still there but filled with sand.

Location of the 'ringstand(1)',at the 'Witte Molenstraat'.
The 'ringstand' will be moved shortly to a new location somewhere between the trees on the right picture.
The 'ringstand' was probably meant for a search light but almost surely not for a machine gun.


Close view.


The other bunker(2) which is not far away but totally covered by plants.  The right picture proofs that this has been used for a machine gun.

The castle before and after the bombing raid. It stood near location number 4 on plan.  Number 5 was the entrance of the MPA.

The large bunker which suffered some exterial damage but successfully served as a shelter.  No damage was made inside the bunker.

Number 4: The 'Wittemolenstraat' looking in the direction of the N31 which didn't exist at the time.  The N31 is the main reason why many buildings have disappeared in the seventies.  The location of the castle is just where the house at the left(partially hidden behind trees) is standing now.

The old City House(Castle Bloemenoord) of Sint Michiels with the monument of WWI and WWII in front of it.
During World War II it was used as a diningplace for the 'Marinehelferinnen' of the MPA.

24 names of the 40 Belgian victims of May 28 1944.


Another 'ringstand(3)' close to a warehouse center.  It is exactly the same as the first one but filled with sand.

First ringstand(1) moved on September 7 2006 to become a monument of the victims of 'Ter Linden'.


Pictures above: approximately taken at 6h45m in the morning just before going to work.
Still not moved but the final place has already been prepared.  Just a matter of time.

Since September 29 2006, officialy a monument. Position 6.

A bomb which has been recovered on December 19 2006.

This is a comment I've got from a correspondent:

'The windmill or propeller device on a bomb is not a timer. It is a safety device that blocks the impact fuse from working if the bomb had not fallen a certain distance from the plane. That safety device was again secured by a safety pin that locket it in place. In B17 bombers they were removed by the crew after takeoff. In some other planes they were fastened to the bomb rack by a lanyard so that the pin was pulled upon release from the plane.
This again let the windmill free to rotate and arm the impact fuse if the bomb was released above the set minimum height.By the way the bomb is of American manufacture, with two fastening lugs showing above the bomb. It probably has a single lug on the opposite side to fit British aircraft.'

Thanks for making this clear,  SMA !

Just behind on the empty field, the original location of the bunker.

My congratulations go to the Bruges city councel for preserving the bunker and protecting it as a monumument for the victims of the bombardment.
I hope the other left over WW1 and WW2 artifacts, especially at the Belgian coast can be preserved in the same was as they did with this one.
