The Lambton Worm is a legend from County Durham in North East England in the UK. The story takes place around the River Wear, and is one of the area's most famous pieces of folklore, having been adapted from written and oral tradition into pantomime and song formats.
The story revolves around John Lambton, an heir of the Lambton Estate, County Durham, and his battle with a giant worm (dragon) that had been terrorising the local villages. As with most myths, details of the story change with each telling.
The story states that the young John Lambton was a rebellious character who missed church one Sunday to go fishing in the River Wear. In many versions of the story, while walking to the river, or setting up his equipment, John receives warnings from an old man (or a witch – depending on who tells the story) that no good can come from missing church.
John Lambton does not catch anything until the church service finishes, at which point he fishes out a small eel- or lamprey-like creature with nine holes on each side of its salamander-like head. Depending on the version of the story, the worm is no bigger than a thumb, or about 3 feet long. In some renditions it has legs, while in others it is said to more closely resemble a snake.
At this point, the old man returns, although in some versions it is a different character. John declares that he has caught the devil and decides to dispose of his catch by discarding it down a nearby well. The old man then issues further warnings about the nature of the beast.
John then forgets about the creature and eventually grows up. As a penance for his rebellious early years, he joins the Crusades.
Eventually, the worm grows extremely large and the well becomes poisonous. The villagers start to notice livestock going missing and discover that the fully-grown worm has emerged from the well and coiled itself around a local hill.
