The Bishop of Chester is the Ordinary of the Church of England Diocese of Chester in the Province of York. The diocese extends across most of the historic county boundaries of Cheshire, including the Wirral Peninsula and has its see in the City of Chester where the seat is located at the Cathedral Church of Christ and the Blessed Virgin Mary, which was formerly the Benedictine Abbey of Saint Werburgh, being elevated to cathedral status in 1541. The Bishop's residence is Bishop's House, Chester. Cheshire previously held a bishopric from 1075 when the seat was at the collegiate church of St John the Baptist until 1102. The present diocese was formed in 1541 under King Henry VIII. Mark Tanner's election as Bishop of Chester was confirmed on 15 July 2020. Earliest times Chester at various periods in its history had a bishop and a cathedral, though till the early sixteenth century only intermittently. Even before the Norman conquest the title Bishop of Chester is found in documents applied to prelates who would be more correctly described as Bishop of Mercia or even Bishop of Lichfield. After the Council of London in 1075 had decreed the transfer of all episcopal sees to cities, Peter, Bishop of Lichfield, removed his seat from Lichfield to Chester, and became known as Bishop of Chester. There he chose as his cathedral collegiate church of Saint John the Baptist, an arrangement which continued until 1102. The next bishop, however, transferred the see to Coventry on account of the rich monastery there, though he retained the episcopal palace at Chester. The Diocese of Coventry and Lichfield was of enormous extent, and it was probably found convenient to have something analogous to a cathedral at Chester, even though the cathedral itself was elsewhere; accordingly we find that the church of St John ranked as a cathedral for a considerable time, and had its own dean and chapter of secular canons down to the time of the Reformation. But the chief ecclesiastical foundation in Chester was the Benedictine monastery of St Werburgh, the great church of which finally became the Cathedral Church of Christ and the Blessed Virgin Mary. The site had been occupied even during the Christian period of the Roman occupation by a church dedicated to Ss. Peter and Paul, and rededicated to St Werburgh and St Oswald during the Saxon period. The church was served by
