Question - Rushden rugby club

[Outlaw Jessie]

Hi folks,

Has anyone come across any underground structures at the above location? I've been travelling around there recently and it looks like there are air vents coming up and its slightly mounded. We've checked all the old records we can find and can't see any bunkers/shelters etc listed as being in this area.

I did have pictures but uselessly can't find them right now, I'll get more....but in the mean time - anyone heard of anything here?

Im pretty familiar with the area & have never noticed these, where abouts in relation to the rugby club are these?
The bypass etc has not been there that long so would of thought anything close would of been filled in when this was built.
I also believe none of the ironstone mines were in this area but may be wrong!
