Footage shows a sinkhole which has appeared in the ground after an old mine shaft caved in near the Botallack Mine in St Just, Cornwall.

According to the filmer, "the hole appeared last month and appears to be widening".

Botallack Mine features as a filming location in popular BBC drama Poldark.

According to the person who filmed the sinkhole, the collapse of an old mineshaft left a gaping hole in a clifftop field.

Cornwall was once rich from the trade in tin, and the area is now dotted by hundreds of old mine stacks, engine houses and unmapped mineshafts.
