Built in 1561 through to 1566, the Astronomical Clock is considered to be a real treasure of both art history and sacred history. It was located behind the High Altar in the ambulatory but was completely destroyed in 1942. Only one dial (which had been replaced with an earlier restoration) remains in the St. Annen Museum. The new Astronomical Clock was constructed on the East side of the Northern transept in the "Death dance" chapel. It is the work of Paul Behrens, a clockmaker in Lübeck, who planned it as his lifetime achievement from 1960–1967, collected donations for it and constructed the elements of the clock himself. He also maintained the clock until his death. The clockface is a simplified duplicate of the original. With a complicated mechanical system, the clock shows planetary positions, phases of the sun and moon, signs of the zodiac (astronomically, not astrologically), the date on which Easter falls and the Golden Ratio. At 12 o'clock midday the bells ring out and the movement of the figures before Christ consecrating spurs into action. The figures were originally Electors; after post-war reconstruction they are now eight representatives of the different races and peoples of the world.
