Astronomical Clock, Prague (must see)

The Astronomical Clock on Prague’s Old Town Square has been drawing curious eyes since the 15th century. Every hour from 9 a.m. to 9 p.m., a theatrical blend of medieval engineering and storytelling never fails to draw a crowd. The clock’s beauty is matched by its complexity, with layers of astronomical and calendar dials showcasing the scientific prowess of its creators.

The main dial presents a symbolic view of Earth and Sky, split between day and night. Surrounding that is a ring showing old Bohemian time, while the astronomical display charts the sun and planets as they orbit the Earth—back when the universe revolved around us, of course. Another circle traces the paths of the sun and moon through the zodiac. A final ring on the edge shows the day, date, and the name of the saint commemorated—a matter of significance in medieval times.

But it’s the show on the hour that captures the most attention. From tiny trapdoors above the clock face, a parade of carved apostles appears, led by Christ, moving steadily past two small windows. Overhead, four figures symbolize medieval threats—Death with an hourglass, Greed clutching gold, Vanity admiring his reflection, and a Turk shaking his head. Below, statues representing Philosophy, Religion, Astronomy, and History observe the scene. As the show concludes, a golden rooster flaps and crows, and the clock strikes the hour to polite applause before the spectators disperse.

Local legend adds an eerie layer: the master clockmaker, Hanus, was blinded to ensure he’d never replicate his work elsewhere. In revenge, he damaged the clock, and no one could repair it for a hundred years. Another tale suggests that if the clock ever stops for too long, the fate of Prague may hang in the balance.

Tip: For a bird’s-eye view, take the elevator—or brave the stairs—to the top of the tower. The view is worth every step.
