 Because of the war damage, the Minster has no medieval windows.But among the modern artworks Essen Cathedral Chapter commissioned during the rebuild, were new windows for the church and modern sacral art, which was to be in harmony with the older elements of the building.The window of St Michael and the windows of the gallery are by Heinrich Campendonk, the choir windows by Ludwig Gies, those of the nave by Wilhelm Buschulte and the windows of the crypt are by Alfred Manessier.
