Prophet’s Mosque Preserves 80-Year-Old Solar Heritage Clock

The Prophet's Mosque preserves an 80-year-old heritage clock that operates on a system that calculates time based on the sun's movement, starting its count at the zenith (noon). This clock serves as a living testament to the mosque's historical evolution in timekeeping, which included the installation of its first mechanical clock near Al-Salam Gate in 1253 AH.

 Historically, the mosque relied on sundials and the movement of shadows to regulate prayer times, demonstrating an early mastery of astronomy and mathematics in the service of religious rites. The continued operation of this clock today highlights the meticulous care given to the heritage artifacts of the Prophet’s Mosque, preserving the technical and scientific legacy that has organized worship for decades.
