The Orloj is mounted on the southern wall of Old Town Hall in the Old Town Square.The clock mechanism has three main components – the astronomical dial, representing the position of the Sun and Moon in the sky and displaying various astronomical details; statues of various Catholic saints stand on either side of the clock; "The Walk of the Apostles", an hourly show of moving Apostle figures ...
Mechanical clocks were a major breakthrough, one notably designed and built by Henry de Vick in c. 1360, which established basic clock design for the next 300 years. Minor developments were added, such as the invention of the mainspring in the early 15th century, which allowed small clocks to be built for the first time.
In 1818 he invented and patented a type of mantel clock, known as the lighthouse clock and regarded as the first alarm clock produced in America. [6] Originally known as the "Patent Alarm Timepiece", they have become known as lighthouse clocks (a 20th-century term) for their obvious similarities.
It is the third clock on that spot and dates from the time of the first French possession of the city (1681–1870). The first clock had been built in the 14th century and the second in the 16th century when Strasbourg was a Free imperial city of the Holy Roman Empire. The current, third clock dates from 1843. [1]
In 1752 Bartolomeo Ferracina started work on replacing the clock, having successfully tendered for the job in public competition.

The Ohio Clock is an 1815 clock in the United States Capitol; The Town Clock of Dubuque, Iowa is in a downtown clock tower, built in 1864. The Clock of the Nations, Rochester, New York was located at the Midtown Plaza in the 1960s. It had dioramas of 12 different nations. Every hour on the hour the dioramas opened up and music was played.
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 ...
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.
