The Astronomical Clock of Prague is one of two main tourist attractions of the city (the other one is Charles Bridge). The square in front of the clock is crowded with tourists every day and especially when the clock strikes the hour when n entire performance happens.
The Astronomical Clock (Prague orloj- Pražský orloj) in Prague is the third oldest astronomical clock in the world and the oldest one that still works. In 1410, it was installed on the southern wall of the Old City Hall in Prague, where it stands even today. It is one the most appreciated tourist attractions of the city of Prague (together with the Charles Bridge).
Every hour (from 09-21h) the two windows above the clock open and one by one wooden figures of the Apostils come out. At the same time, two figures on each side of the clock will start to move, while the whole performance will end with the movement of the golden rooster on top of the clock.
The clock consists of two main dials: the Clock dial and the Calendar dial (the lower circle).
The clock dial was a brilliant achievement of that time. The blue background of the clock represents the sky above the horizon, brown color stands for the sky below the horizon. Above the line of the horizon there are inscriptions in Latin: East and West, and under the line it says Dusk and Dawn. The zodiac ring of the clock moves accordingly and shows visible star conciliations. Finally, the Dial with the Sun and the Moon also rotates showing the movement of these astrological objects. The Moon is represented as a silver ball that shows the phases of the Moon.
Visitors will notice there are three different sets of markings on the clock. Actually, the clock was able to give three different presentations of time: Old Czech time (Italian time), Central European time and Babylonian time.
Calendar dial was a later addition to the Astronomical clock. This dial shoes the current month (represented by the medallion picture allegory of every month), the current day (all days are written on the outer layer of the calendar but the current one is shown on top of the clock) and the zodiac sign.
