Aarhus Cathedral has a number of fresco paintings dating from the 1470 to 1520. Until the Reformation, most of the church's walls were covered in frescoes, of which many were lost. The cathedral still has 220 m2 of frescoes, more than any other church in Denmark. One pre-1470 painting was saved from the first Romanesque-style cathedral in the northwest corner, the so-called Lazarus Window, painted about 1300. It is believed that the window was used to give food to the lepers who weren't permitted inside the building.The paintings of St Christopher and St Clement are the tallest in the country.St Clements only has one stained glass window. It was created by the Norwegian artist Emanuel Vigeland in 1926. Its theme is taken from Grundtvig's psalm Da livtræet fæstet i graven rod. It stands 14 m high and is the largest stained glass window in all of Denmark. Three scenes are painted on the window: at the bottom, Christ's lying in his grave on Golgotha; next, Christ crucified, and topmost, Christ standing in golden light. .
