Astronomical clock
The original astronomical clock was built in 1561–1566. It used to stand in the ambulatory, behind the high altar but was completely destroyed in 1942. Only a clock dial that was replaced during a previous restoration remains, in St. Anne's Museum The new Astronomical Clock, which was installed on the East side of the Northern transept, in the Danse Macabre Chapel. It is the work of Paul Behrens, a Lübeck clockmaker, who planned it as his lifetime achievement from 1960 to 1967. He collected donations for it, made the clock, including all its parts, and maintained the clock until his death. The clock front is a simplified copy of the original. Calendar and planetary discs controlled by a complicated mechanical movement show the day and the month, the position of the sun and the moon, the signs of the zodiac (the thirteen astronomical signs, not the twelve astrological signs), the date of Easter, and the golden number.At noon, the clock chimes and a procession of figures passes in front of the figure of Christ, who blesses each of them. The figures originally represented the prince-electors of the Holy Roman Empire; since the post-War reconstruction, they represent eight representatives of the peoples of the world.
