The Chapel of the Virgin is decorated with The Patron Saints of Cologne (c. 1440), an altarpiece produced by Stephan Lochner, the most important artist of his time in Cologne, while a stained-glass window in the southern transept lends a contemporary touch to the cathedral. The modern art sculpture, created by famous German artist Gerhard Richter, is made up of about 11,000 equally sized glass pieces in 72 hues. Finally, it is stated that the magnificent wooden statue depicting the Virgin Mary carrying Jesus possesses mystical abilities.
