John was imprisoned in the Tower of London until allowed to go to France in July 1299. When his baggage was examined at Dover, the Royal Golden Crown and Seal of the Kingdom of Scotland, with many vessels of gold and silver, and a considerable sum of money, were found in his chests. Edward I ordered that the Crown be offered to the shrine of St Thomas Becket at Canterbury, and that the money be returned to John for the expenses of his journey. But he kept the Seal himself. John was released into the custody of Pope Boniface VIII on condition that he remain at a papal residence. He was released around the summer of 1301 and lived the rest of his life on his family's ancestral estates at Hélicourt, Picardy.
