Canterbury is a cathedral city and UNESCO World Heritage Site, situated in the heart of the City of Canterbury, a local government district of Kent, England. It lies on the River Stour.

The Archbishop of Canterbury is the primate of the Church of England and the worldwide Anglican Communion owing to the importance of St Augustine, who served as the apostle to the pagan Kingdom of Kent around the turn of the 7th century. The city's cathedral became a major focus of pilgrimage following the 1170 martyrdom of Thomas Becket, although it had already been a well-trodden pilgrim destination since the murder of St Alphege by the men of King Canute in 1012. A journey of pilgrims to Becket's shrine served as the frame for Geoffrey Chaucer's 14th-century classic The Canterbury Tales.
