For Christians, the journey to the Cathedral at Santiago de Compostela is rivaled only by a visit to the Holy Land. With over 100,000 pilgrims a year, it is one of the fastest growing pilgrimage destinations in the world and with this year's holy year celebrations, they are expecting some very special guests. The King and Queen will celebrate St James day and the Pope will say Holy Year mass for thousands. There's only one problem. Before this happens restorers must race against time as stonework, the famed Portico de la Gloria the Botafumeiro, and relics, all get makeovers.
