Today is the feast of the Decollation of St John the Baptist and thanks to John Dillon's posting today on the Medieval religion discussion group I can share some images and details of relics believed to be those of St John.
What is reputed to be the head of St John has been kept as a relic in Amiens cathedral since the early thirteenth century:

The reliquary is an 1876 reconstruction of that presented by King Charles VI in 1385.

There is more information in French about the relic here.
The pilgrimage of King Louis X and Queen Clemence to this relic in Amiens is described in Maurice Druons's wonderful Les Rois Maudits, and dramatised in the classic television version of the early 1970s - one of the best, if not the best, television historical dramas, and which really gave a feeling of medieval life, but I will write more about that on another occasion. That particular royal pilgrimage resulted in the birth and very brief life and reign of King John I in 1316.
