Prague Astronomical Clock, Medieval astronomical clock at Old Town Square, Czech Republic.
The astronomical dial displays the positions of the Sun, Moon, and zodiac constellations through an intricate system of mechanical components on the southern wall.
Clockmaker Mikuláš of Kadaň and astronomer Jan Šindel created this mechanical masterwork in 1410, establishing it as the world's third-oldest astronomical clock.
The clock mechanism presents an hourly parade of twelve apostle figures accompanied by a bell-ringing skeleton, representing the cycle of life and death.
Visitors can observe the clock's mechanical performance every hour between 8:00 AM and 11:00 PM, with the best viewing spots directly in front.
The clock combines four different time measurements: Babylonian time, Old Czech time, German time, and Sidereal time through separate mechanical systems.
