Salisbury Cathedral is well-known for its many relics.  Probably the most important relic is one of the four original copies of the Magna Carta.

This cathedral holds probably the best preserved original copies of the Magna Carta.  All in all there are four copies.  The other copeis are located in the Lincoln Castle and British Library.  The Magna Carta is held in the Chapter House and visitors can see it as they tour the Cathedral.
