Children from the Minster School came to watch the wreath being prepared and then suspended 50ft (15m) up in preparation for Christmas.
The wreath is assembled each year by York Minster's team of volunteer flower arrangers, who collect ivy from Dean's Park and other locations around the city.
A giant advent wreath at York Minster has been hoisted up in the central tower.
