Astronomical Clock Prague

Also known as Pražský orloj

The Orloj has been tracking time in Prague's Old Town Square since 1410, making it the oldest still-functioning astronomical clock in the world. It displays five simultaneous time systems at once, including Babylonian and Old Bohemian time, and the four flanking figures represent 15th-century fears: Vanity, Greed, Death, and the Ottoman Turk.

Prague’s Astronomical Clock on the Old Town Hall has operated since 1410, making it the oldest functioning astronomical clock in the world. The face displays five time systems simultaneously, and the four flanking figures representing Vanity, Greed, Death, and an Ottoman Turk capture 15th-century Christian European anxieties with unusual directness. The mechanical apostle procession runs on every hour. The clock is viewable for free from the square at any time; tower entry costs around EUR 7. Metro Line A to Staromestska. Early morning visits are significantly less crowded.
