The abbey grew in importance and elaboration, alongside the "City of the Castle". This was a major commercial centre, under the patronage of the abbot, and outside the boundaries and control of the Cathedral City, dominated by the bishop. The body of Saint Martial was, at some time in the late 9th century, taken from its sarcophagus and placed for a time in a golden shrine in the great new church which was built over the spot. Here it was a magnet for pilgrims on the Way of St. James, benefiting from the wider pilgrim traffic throughout Western Europe.
