The archbishop oversees the Province of Canterbury that is all the Church of England dioceses in the south and midlands of England. The dioceses of Wales were also within the Province of Canterbury until 1920 when the Church in Wales became independent. In the north of England another archbishop has the Diocese of York and other northern dioceses (including the diocese of Sodor and Man) to oversee. Both archbishops are members of the House of Lords and rank very high in the official English order of precedence. When a new monarch is crowned the placing of the crown on his head is done by the Archbishop of Canterbury. The principal home of the archbishops is at Lambeth Palace in the south of London rather than at Canterbury itself. Within the Diocese of Canterbury (which consists of eastern Kent and a small enclave in Surrey) the archbishop has at least two assistant bishops.
