In the course of the repairs to the tower façade in 2006-2007, the bells were removed, cleaned and repaired. The bell holder was equipped with a suspension made of stainless steel, and other important parts were replaced including the springs and cables. The total renovation cost was 750,000 Euro, which was for the most part donations from the citizens of Munich (660,000 Euro), the German Foundation for the Protection of Historical Monuments donated an additional 100,000 Euro. The bells were re-installed, revised, and tuned in time for the 850th birthday of the city of Munich in 2008.
