After the celebrations marking the seventh centenary of the start of building work on the cathedral in 1948, children of Cologne donated money for a stained glass window in the cathedral. The window was designed by Bernhard Kloss between 1960 and 1965. It shows scenes featuring children in the Old and New Testaments and in the life of the Church. The fourth scene from the bottom in the outer, right-hand lancet shows the children of Cologne collecting money for the window.
