Did seven monks carry The Grail from Glastonbury Abbey at the time of the Dissolution of the Monasteries in 1539, to the Cistercian Abbey of Strata Florida in Mid Wales? The mystery of the Nanteos Cup and its healing powers has fascinated and intrigued for 300 years. The theft of the Nanteos Cup from a private home in Wales in 2015—and its even more remarkable recovery two years later—made the headlines in most major newspapers and featured on BBC Crimewatch. People who had never heard of the cup began asking what it is—a question that has occupied people for the past three hundred years, since word of this mysterious vessel first began to filter out to the world. Though unremarkable to look at, stories of the cup’s powers and of the miraculous cures experienced by those who drank from it have been in circulation for years. At some point it became associated with one of the most enduring stories of all time—the Holy Grail.
