A woman who thought she had uncovered a hidden sinkhole in a St Paul's Cray field has been told it is actually a man-made 'dene hole'.
Dene holes are historic structures used traditionally for either storing grain, hiding, or mining for chalk or other resources.
Michelle Woodfine spotted the cavity, which is approximately 20ft deep, while walking in a farmer's field behind St Paul's Cray Hill Park, close to an area of woodland.
She says she and her husband came across the opening, which is hard to spot due to long grass, after taking a detour while making their way to towards Chapman's Lane.
Mrs Woodfine added the hole looks deep enough that if someone were to fall in they would not be able to get out unaided.
She contacted Bromley Council about her discovery, who said the land in question is privately-owned, but will act due to safety concerns.
The council told Mrs Woodfine: "Please be advised the area of land in question does not belong to
LBB, it is privately-owned and the public have no right of way or access to this land.
"However, due to potential risk of serious injury/fatality, LBB Parks Rangers have investigated & located the 'dene hole' which is, in fact, man-made.
"Though LBB are not obliged to do so, we will be erecting a hazard warning around this this hole
in the interests of public safety as it is evident members of the public do access this land, albeit at their own risk and without permission.
"The lanowner will be informed."
