Zimmer Tower

The Zimmer Tower, located in the Belgian city of Lear, Belgium, was supposedly built in 1425 from gray stone as part of the city's fortifications. For some time it was owned by private owners who used it for various purposes. After the First World War, the tower was demolished. This decision was changed after in 1928 the watchmaker Louis Zimmer gave the city the Jubilee Clock – a real masterpiece. The clock with 57 dials, 13 of which are located on the outer facade of the tower, show the time of all time zones, the phases of the moon, the tides and many other periodicals. The tower was thus preserved and named after the watchmaker.

The next gift of Louis Zimmer was the so-called Wonder Clock with the slowest hand in the world, the turnover of which will last 25800 years, which is equal to the precessional period of the Earth's axis. The clock was created in 1935, later the master attached a mechanical planetarium to them, and in 1960 a special pavilion was built next to the Zimmer Tower for their storage. Since 1980, the tower and the pavilion next to it, which is now a museum, are included in the list of historical monuments protected by the Ministry of Culture of Belgium. The square near the tower is an image of the scheme of the solar system, made of metal circles and rings.
