The earliest depiction of a clock powered by a hanging weight is from the Bible of St Louis, an illuminated manuscript made between 1226 and 1234 that shows a clock being slowed by water acting on a wheel. The illustration seems to show that weight-driven clocks were invented in western Europe. [79]
The following is a list of notable companies that produced, or currently produce clocks. Where known, the location of the company and the dates of clock manufacture follow the name. In some instances the "company" consisted of a single person.
Many big and complex clocks with automated figures were built as public spectacles in European town centres. One of the earliest of these large clocks was the Strasbourg astronomical clock, built in the 14th century which takes up the entire side of a cathedral wall. It contained an astronomical calendar, automata depicting animals, saints and ...

The Astrarium, which he designed and built over a period of 16 years, was a highly complex astronomical clock and planetarium, constructed only 60 or so years after the very first all-mechanical clocks had been built in Europe, and demonstrated an ambitious attempt to describe and model the planetary system with mathematical precision and ...
The escapement is just below it. From his 1364 clock treatise, Il Tractatus Astrarii. The verge escapement dates from 13th-century Europe, where its invention led to the development of the first all-mechanical clocks. [3] [9] [10] Starting in the 13th century, large tower clocks were built
Clocks like these were built from the 1st century BC through to Victorian times in Europe. A cuckoo clock is a simple form of this type of clock. The first known mention is of those created by the Roman engineer Vitruvius, describing early alarm clocks working with gongs or trumpets. [3]
A facade was added in 1529 when the clock was moved to its current position. [3] The mechanism was electrified in the 1920s and it was restored in 1997. [citation needed] As of 9 July 2022, the clock movement itself is not functional in any way. There is an electrical solenoid that rings one of the two bells in the tower on the 1/4 hr.
