    Mounted on the southern wall of Prague’s Old Town Hall, the Astronomical Clock is a marvel of Gothic and early Renaissance engineering. More than just a timekeeper, it displays the positions of the sun and moon, zodiac signs, and a calendar dial adorned with medallions of the months. Each hour, crowds gather below to watch the animated figures of the Twelve Apostles and allegorical sculptures come to life in a centuries-old ritual.

    What to Expect

    Your visit centers on the hourly “show”—from 9 AM to 11 PM—when the two small trapdoors open and wooden Apostles march past windows above the clock face. Meanwhile, the four flanking statues (Death, Vanity, Greed, and Lust) animate in a playful yet macabre tableau. Beyond the spectacle, admire the richly painted Calendar Dial by Josef Mánes and the zodiacal Astrolabe with its moving celestial spheres.

    Inside the Old Town Hall tower, a small exhibition details the clock’s history and craftsmanship. Climb the spiral staircase to reach the viewing gallery for panoramic vistas of Old Town Square’s Gothic spires and red-tiled rooftops.

    Background and Cultural Context

    Installed in 1410 by clockmaker Mikuláš of Kadaň and astrologer Jan Šindel, the Orloj originally had only the astronomical and calendar dials. The wooden Apostle figures were added around 1490, and later restorations in the 18th and 19th centuries introduced Gothic and Neo-Renaissance embellishments. Legend holds that the city blinded the original maker to prevent replicas—a myth that underscores the clock’s cultural mystique.

    Throughout wars, revolutions, and fires, the Orloj has been meticulously repaired and preserved. Its enduring presence in Old Town Square makes it not only a technical wonder but also a symbol of Prague’s resilience and artistic heritage.

    Best Time to Visit

    Arrive 10–15 minutes before the hour to secure a good vantage point on the square. Early morning (9 AM–10 AM) and late evening (after 9 PM) offer fewer crowds, while twilight hours add dramatic lighting to photos. Avoid midday on weekends if you prefer space to move and clear sightlines.

    How to Get There

    The clock is on Staroměstské náměstí in Prague’s Old Town, a two-minute walk from Staroměstská metro station (Line A) or tram stops “Staroměstská” (Lines 17, 18) and “Staroměstské náměstí” (Lines 2, 17). Follow signs for the Old Town Hall tower and join the gathering beneath the clock face.
