Lichfield Cathedral, formally the Cathedral Church of Saint Mary and Saint Chad in Lichfield, is a Church of England cathedral in the city of Lichfield, England. It is the seat of the bishop of Lichfield and the principal church of the diocese of Lichfield and holds daily services. The cathedral has been designated a Grade I listed building.
The diocese of Mercia was created in 656, and a cathedral was consecrated on the present site in 700. The relics of the fifth bishop, Chad of Mercia, were housed at the cathedral until being removed in 1538 during the English Reformation. In 1075 the seat of the diocese was moved to St John the Baptist's Church, Chester and then from there to St Mary's Priory in Coventry. Lichfield gained co-cathedral status in 1148, and became the sole cathedral in the diocese after St Mary's Priory was dissolved in 1539 and the new diocese of Chester created in 1541. During the English Civil War the Cathedral Close, Lichfield was besieged three times; the church was severely damaged, losing all of its medieval glass and many monuments.
