There are many threats to burial grounds, but they all have one common cause - neglect.
Lack of funding has led to this neglect in some cases, but in the case of Warrington and it's closed burial grounds, Warrington Borough Council have a lot to answer for.
There are around 9 cemeteries that they are responsible for the maintenance of, as well as their own burial grounds.
(It is impossible to give an exact number as the council website does not mention any of these sites)
Nearly all of these are overgrown and neglected.
