The purpose of deneholes was subject to some speculation during the 19th Century, but they are now believed to be ancient chalk mines. They are found in areas where opencast mining would not be possible, and take the basic form of a number of chambers accessed by a vertical shaft. There were many hundreds and most were filled in after the chalk was extracted, but over the years some have collapsed revealing very dangerous open shafts. This one, located in Darenth Wood near Dartford, is unusual in that it is accessable due to one of the chambers having collapsed.
This Denehole is on open land, but if visited appropriate care should be taken.
