The world's largest hourglass, located in the Natural History Museum in Mainz, is a special landmark. It is not only the largest but also one of the most accurate hourglasses in the world.
The glass bulbs rotate every hour on the hour, controlled by a computer system. The hourglass is made of Duran borosilicate glass and is 5.2 meters high and one meter in diameter.
The hourglass, which originally stood on the town hall plateau, was later moved in front of the Natural History Museum. It was a gift from the Schott company and was briefly threatened with scrapping, but was restored and put back into operation.
The hourglass is a popular tourist destination and attracts many visitors.
The hourglass is not to be confused with the Wheel of Time in Budapest, which is also considered one of the largest hourglasses in the world, but runs for one year. The Mainz hourglass is a one-year hourglass and weighs one ton of sand. In summary, the hourglass in the Natural History Museum in Mainz is an impressive construction and a popular landmark of the city.
