Situation August 15 2011

Plan from 'After the Battle', number 6 showing a situation from the Colonel Sanders report.  Only the Main building and a 'Generator' bunker was found in the dense forest.
Nearby there's a Railroad which must have been used by the Germans and is now beëing used for amusement purposes only.
Good preserved trenches and many craters can be found near the large bunker.

Not all building formations, concrete blocks, reservoir and Air Raid tunnels were found or visited.

Lottinghen is one of the 'Wasserwerke' which meant to be large bunkers for launching V1's to London, UK. The longitudal axis of this bunker stands perpindicular to the launch direction which I measured to be almost 290 degrees.  This is interesting because this is the launch direction to the London area.

The construction of the 'Wasserwerke' was decided by Herman Goering on June 18 1943.  Original plans were bunkers of 135000 cubic metres.
They were later reduced to 55000 cubic metres(which is still very impressive !).  The dimensions of the bunker should have been 212.3m long and 36.2m wide.  But other sources give different numbers like 212.62m long and 48.8m wide.  Only the bunker of Siracourt was almost complete with a length of 178.1m.
The bunker of Lottinghen is also very impressive but didn't pass stage 4(from 6 stages) in its completion.  5000 workmen were at this site.
Beëing bombed for the first time on February 24 1944, the site was abandonned at the end of april 1944.

A list of Wasserwerke

- Wasserwerk Desvres - Lottinghen
- Wasserwerk 1 St Pol - Siracourt
-Wasserwerk Bauwerk 7(B7) Valognes - Tammervile
-Wasserwerk 8(B8) Cherbourg - Couville

No FZG76 has ever been launched from these sites, at least 150 V1's could be stored in the Wasserwerk bunkers.
This means that 5 days of operations would be possible.
The future however of these bunkers has never been assured but 3th generation V1 sites which were very simplified seemed to be the most successfull ones.

GE KMZ file with the location of the bunker.  From above, there's nothing to see but during WWII there were no trees over there.


Left: The nearby railroad,use for amusement manpowered railroad wagons.  You can make a trip of 10km with it.  It is a former German railroad certainly used to deliver V1's.
Right: huge bomb crater.  The site has been bombed with code name Crossbow Noball XI/D/4.


The Electro Bunker.(I'm not sure about it but I did not find any documentation about it)

Some fundations, probably R on plan from Colonel Sanders.

Beneath the fundaments of the enormous amount of concrete.


The Colonel Sanders report of construction fases of this heavy V1 bunker.  The Lottinghen bunker only reached fase 4.


Left: Well preserved trenches.  Right: the bomb shattered pieces from the bunker.

Bomb shell with my GPS as a comparison.

 Compare with the V1 Wasserwerk of Siracourt St Pol
