The Devil's Chimney is a rock formation on Leckhampton Hill, south of Cheltenham, Gloucestershire, England.
It is a largely man-made pillar outcrop, formed when an incline to a quarry was cut behind it, isolating the pillar from the main hillside.[1] It is named for its peculiar shape, that of a crooked and twisted chimney rising from the ground. The Devil's Chimney is a local landmark, but its origins are uncertain. In 1926 it survived an earthquake, but not without a few cracks. In 1985 it was repaired and protected from further erosion.
