The story of King John’s lost treasure is one of the most fascinating folklore tales associated with the area near latitude 51.2863889 and longitude -2.7602778. The tale dates back to AD 1216 when King John of England was making his way from Bishop’s Lynn (now King’s Lynn) in Norfolk towards Lincolnshire. As history goes, the king was suffering from dysentery and was unable to control his troops. In the twist of events, it is said that he lost all of his treasure in the Wash, a square-mouthed bay and estuary on the northwest margin of East Anglia on the east coast of England. The legendary treasure is believed to include the Crown Jewels, countless gold, silver goblets, and coins worth a fortune. Imported silks, furs, spices, and other valuable items collected over years were also said to be part of this lost bounty. Despite numerous expeditions since then, the treasure of King John’s lost gem-studded crown, his sword, and the golden chain has never been found. Many attribute the missing treasure to the whims of the marshy geography while others believe it to be sunk deep beneath the silt and sand, waiting to be discovered someday. This tale has become an integral part of the regional folklore and has secured its place in England’s rich tapestry of legends and myths. Even today, after hundreds of years, the story holds an air of mystery and continues to spark the interest of treasure hunters and historians alike.
