Canterbury, a cathedral city in southeast England, was a pilgrimage site in the Middle Ages. Ancient walls, originally built by the Romans, encircle its medieval centre with cobbled streets and timber-framed houses. Canterbury Cathedral, founded 597 A.D., is the headquarters of the Church of England and Anglican Communion, incorporating Gothic and Romanesque elements in its stone carvings and stained-glass windows.
Canterbury was issued with the 84 Post Office numeral in 1844
