What is a hag stone used for?
A hag stone, also called a holey stone, witch stone or adder stone, is any pebble with a naturally formed hole right through it. Most are flints or limestones bored by water or by burrowing sea creatures. Folk custom gave them a protective job: tied above a bed against the nightmare, hung in a stable so that horses would not be ridden at night by the hag, nailed to a door, or fastened to the bow of a boat.
The name comes from that use. The hag was the night spirit believed to sit on sleepers, and the stone was what kept her off. A second belief, that looking through the hole lets a person see fairies or see through enchantment, belongs to the same family of customs. The hole has to be natural; a drilled stone did not count.

What sets Hag Stone apart
What makes a hag stone is the one thing no craftsman can supply: a hole made by nature. Custom rejected drilled stones, so each charm had to be found, and finding it was part of its worth. The second rule is placement. A hag stone was not worn like a jewel so much as stationed, at the bed head, the stable door, the key ring or the boat's bow, wherever the night hag or ill luck might get in.
- Other names: holey stone, witch stone, adder stone
- Usual material: flint or limestone, holed by water or by boring clams called piddocks
- Early record: John Aubrey, Miscellanies, 1696: a holed flint hung by the manger
- Stable use: hung to stop horses being hag-ridden, found sweating at dawn
- Sea use: tied to the bows of boats by Dorset fishermen, as folklore collectors recorded
Often mistaken for something else: A witch bottle is made, filled and hidden to send harm back on a witch; a hag stone is found ready made and hung in plain sight to keep her out.
The story behind Hag Stone
John Aubrey's Miscellanies (1696) records that a flint with a natural hole was hung by the manger to keep horses from being hag-ridden. Folklore collectors of the nineteenth and twentieth centuries found the custom along the English coasts, with fishermen in Dorset tying holed stones to their boats. The Welsh and Scottish adder stones are often ancient glass beads, said in legend to be made by snakes, a story Pliny had already told of the Druids.
Why Hag Stone matters
Hag Stone shows how ordinary household protection worked in practice: a found object, a fixed place to hang it, and a named danger it was meant to keep out.
How to read Hag Stone
People still collect them from beaches and hang them on keys, doors or bedposts, mostly as a keepsake of the old custom and a small ritual of feeling at home.
Hag Stone in practice: an example
A walker on a shingle beach who finds a flint with a hole through it and threads it on string by the back door is repeating a custom Aubrey wrote down in 1696.
Where readings of Hag Stone go wrong
The stone is a folk custom with no tested effect; troubled sleep that goes on is a matter for a doctor.

In folk custom it was hung over beds, in stables, on doors and on boats to keep off witches, nightmares and misfortune. Today most people keep one as a traditional good luck piece.

The hole is made by nature. Running water and grit can wear through a weak point in a pebble, and on the coast piddocks, a kind of boring clam, drill into soft stone and leave neat holes.

The hag was the night spirit once blamed for nightmares and for horses found sweating at dawn, said to have been hag-ridden. The stone was the charm hung up to stop her.
