According to local legend if you keep a stone like this in your home, a witch may never cross the threshold.
The hole is made by a mollusc called a piddock, and a very small whelk has taken up residence on the edge of its cousin's former burrow.

Hm... are you certain? About the mollusc, I mean. Where I live, rocks by rivers often have these holes in them; we're told they were formed during the Ice Age, when rocks were trapped under the ice and sort of rolled around, drilling holes. Sometimes, you can find rocks still in the holes.

Then again, I seem to remember having read somewhere that nobody really knew what formed them. Molluscs digging great holes in granite several hundred miles from the sea does seem a bit unlikely, though...
