Canterbury Cathedral, detail of window in Trinity Chapel showing the Shrine of  St. Thomas Becket.
© Raguin/MMK.  The shrine was designed by Elias of Durham sometime between 1205 to1216 (destroyed by Henry VIII).  Faced with gold and decorated with jewels, it stood on an elevated base in the middle of the Trinity Chapel, at the east end of the church.  Pilgrims walked around the shrine, framed by windows of the miracles of Becket (as Chaucer says), "the holy blissful martyr, who helps (pilgrims) when they are sick.".
