After the building at Crowland was damaged by fire, there was no longer a suitable place for keeping the relic, so it went to Grantham for safe-keeping. For two or three hundred years, it was kept in the crypt chapel below the Lady Chapel, where the pilgrims helped to wear the hollow, now to be seen in stone step before the altar. Later, towards 1350, the arm went to the specially added chapel above the north porch. At some stage in the long process of the English Reformation, this relic was lost.
