Sundial

A sundial is a timekeeping instrument in Prague that combines bronze numerals, decorative stone carvings, and mathematical calculations to show the correct time. The design uses the sun's shadow as a pointer and requires precise geometric markings that change with the seasons.

This timekeeping instrument originated in the Renaissance when Prague became a center for astronomical studies under Rudolf II's rule. The development of such instruments was closely connected to growing scientific interest in astronomy and mathematics.

The sundials carry traditional Czech motifs and astronomical symbols that reflect how medieval craftspeople understood the sky and time. These decorative choices show what knowledge and skills mattered to the people who built them.

These timekeeping instruments are scattered across Prague's old town in different locations, with guided tours available during warmer months. Strong sunlight around midday helps you see the markings and details clearly.

The markings on this sundial are specifically adjusted for Prague's geographical position to enable accurate time readings at this latitude. These localized calculations show how craftspeople of the era applied knowledge of geography and celestial mechanics.
