York Minster is the cathedral of York, England, and is one of the largest of its kind in Northern Europe. The minster is the seat of the Archbishop of York, the second-highest office of the Church of England, and is the cathedral for the Diocese of York. It is run by a dean and chapter, under the Dean of York. The formal title of York Minster is "The Cathedral and Metropolitical Church of St Peter in York". The title "minster" is attributed to churches established in the Anglo-Saxon period as missionary teaching churches, and serves now as an honorific title.
