If you are in London it is well worth a visit to the Museum of London's medieval gallery. In 2004 I was fortunate to spend some time with John Clark, the curator, who took us into the depths of the museum and showed us two trays of metal Santiago souvenirs not on display. You can see them here: http://www.museumoflondon.org.uk/piclib ... sp?id=1087 A good resource for learning more is Brian Spencer's "Pilgrim Souvenirs and Secular Badges". He examines the souvenirs collected at centres of religious attraction as well as finds from excavations in London during the 1970s to early 1990s, mainly from waterfront sites. Copies of one of the medieval metal scallop shells on display (I think it is exhibit No.33) is sold by the CSJ as a small brooch. Next to it is a small jewelled cross with a hidden cavity, thought to be a reliquiary containing a tiny sliver of the true cross embedded in wax. Stirring stuff!
