Just thought I'd post some photo's and info I have from a visit I made last year to the area around former
fliegerhorst Deelen.
The main part of the tour, which is organised by the Deelen Research Group, consists of a visit to the Diogenes bunker which still exists today. It is now in use as an auxillary depot for the national archive.
The bunker is 60x40x16 meters, with wall up to 3 meters thick. Even though the allies must have known of it's existance it was never bombed during WW2. During operation Market Garden the Germans left the place, but only after they set off two bombs in the main central hall.
This hall was cleaned up after WW2, but it is not open to the public.
Three of this bunkers were built in Europe during WW2; the one in Deelen, one in Groves in Denmark and one in Metz in France. The last one no longer exists, while the one in Denmark is on military grounds and is not accessible for the general public. Each bunker served as a control point for the Kammhuber linie.
Here's a general overview of the area north from Arnhem in Google earth; the Fligerhorst was much larger than the current Deelen AB is.
1: The blocked out area is Deelen AB as it is in use today. One can still see the typical 'A' shape of the three runways, typical of German WW2 fields.
2: The Glider field 'Terlet'.
3: Here is a farm that is housed inside several German hangars.
4: Just right of the '4' is the location of the Diogenes bunker; this was just outside of the Fliegerhorst.
5: In the woods here are several German parking area's for their fighters.
6: The location of the small Deelen museum, located in a former German building.
The Diogenes bunker in close up; clearly visible today but it was camouflaged during the war:
Here we see the farm; three hangars, one larger for a Do-217 or Bf-110 and two smaller ones for 109's.
A close up look of #5: the road used to be a former taxiway.
