Over the centuries a number of things have been removed from Edward the Confessors tomb. These include:
1098 – An attempt was made to pull out a strand of hair.
1163 – His robes were removed and remade into three copes. They were used at coronations. They were probably destroyed as a result of the English Civil War. The pilgrims ring was removed. It was put in a box with other relics. This box disappeared during the reformation.
1685 – Crucifix and gold chain. Stolen from James II as he fled England in 1688.
As far as I know, no part of his body was removed to make relics.
