The site of this former PoW Camp has as expected been lost to modern development in that a housing estate is now to be found in its place. This estate is a typical 1970s / 1980s estate except that it gives an impression of compactness with lots of additional pathways and alleys thought.
The St Neots local history WordPress website gives details as to the former PoW camp at the web link at the bottom of this page. In addition, to defining the location of the four corners of the site:

• TL 189 626
• TL 191 626
• TL 189 624
• TL 191 624

The above figures are broadly in line with the English Heritage Data, but more importantly are consistent in terms of the street lay out on the map and the general size of a PoW Camp. On the ground the site was very much as expected, and I found some interesting some locations and shoots the most interesting of which in term of a WWII was a mural painted within a bus stop.
