Why do people go on pilgrimages to canturbury?

In The Canterbury Tales, Geoffrey Chaucer describes the pilgrims who go to Canterbury to visit the shrine of Saint Thomas a' Beckett. Beckett was the Archbishop of Canterbury who was murdered in the cathedral. People go to the shrine as an act of spiritual rebirth, and, says Chaucer, to visit the shrine "of him who helped them when they were sick."
