In 1283 Edmund son of Richard, Earl of Cornwall holders of Berkhamsted Castle (two and half miles away) founded a monastery at Ashridge, Hertfordshire. The monastery was built for a rector and twenty canons who formed, according to the seventeenth-century historian Polydore Vergil, "a new order not before seen in England, and called the Boni homines". It was finished in 1285.
At the foundation of the abbey the Earl of Cornwall donated, among other things, a phial of Christ's blood, in honour of which the convent adjacent to the abbey was founded. This deposit proved fruitful for the abbey and convent, as pilgrims from all over Europe flocked to see the phial of blood. The abbey grew quite wealthy as a result.
The suppressed college was granted first to the king's sister Mary Tudor (daughter of Henry VII). It later became the private residence of the future queen Elizabeth I. It was here that she was arrested in 1554, under suspicion of treason.
