The condition and measures taken for the conservation and restoration of the stained glass are described. Surplus leading on the original stained glass was removed and the broken glass was mended. The panels were embedded, with the help of an acrylfilm, between modern glasses which were individually curved (Jacobi safety glass technique). Since the double panels are now thicker, new leading was required. The old lead was stored. This method has given good results over several decades in Cologne. R.W. -- AATA
