<P> Trinity Chapel at the east end of Canterbury Cathedral forms part of a UNESCO World Heritage Site . It was built under the supervision of the master - masons William of Sens and William the Englishman as a shrine for the relics of St. Thomas Becket . The shrine became one of the most popular pilgrimage sites in England . </P> <P> The chapel was constructed between 1179 and 1184, replacing a much smaller chapel of the same name destroyed by fire, along with much of the rest of the choir, in 1174 . Its predecessor was where Becket celebrated his first mass following his installation as Archbishop of Canterbury . </P> <P> In 1220, Becket's remains were translated from his first tomb to the finished chapel . As a result of this event, the chapel became a major pilgrimage site, inspiring Geoffrey Chaucer to write The Canterbury Tales in 1387 and with routes (e.g. from Southwark (Chaucer's route) and the Pilgrim's Way to / from Winchester) converging on the cathedral . Becket's shrine stood until it was destroyed in 1540 . This was done on orders from King Henry VIII as vengeance for his ancestor, Henry II . The king also destroyed Becket's bones and ordered that all mention of his name be obliterated . The pavement where the shrine stood in the chapel is today marked by a lighted candle . Modern day archbishops of Canterbury celebrate the Eucharist at this place to commemorate Becket's martyrdom and the translation of his body from his first burial place to this chapel . </P> <P> Over time other significant burials took place in this area such as Edward Plantagenet (the Black Prince), who was interred on the south side of Becket's shrine . His tomb consists of a superb gilded copper effigy beneath a tester depicting the Holy Trinity, with his heraldic achievements hung over the tester . The achievements have now been replaced by replicas, though the originals can still be seen nearby, and the tester was restored in 2006 . </P>
