Whoever failed to carry out this duty was supposed to have to undertake the pilgrimage after death, advancing by one coffin-length every seven years… Today, ever increasing numbers make the same journey, in groups or alone, retracing the steps of the earlier pilgrims.

In 2002, after successfully completing the seven-year tour, the pilgrimage moved on to Wales, whence many of the bishops came.
