Sion astronomical clock, Astronomical clock at town hall in Sion, Switzerland
The clock mechanism displays time through five dials, including two lateral 12-hour faces and a principal dial indicating astronomical information and zodiac signs.
Originally installed between 1667 and 1668 at the Sion town hall, the clock received a mechanical upgrade in 1902 to ensure continued precision.
The clock incorporates classical deities to represent days of the week, connecting timekeeping with traditional European astronomical and mythological elements.
Visitors can observe the clock's display of hours, minutes, zodiac signs, lunar phases, and celestial positions from the town hall square.
A double-ended fleur-de-lys hand points to hours while a specialized golden sun indicator shows both solar position and nighttime constellations.
