Besançon astronomical clock

The Besançon astronomical clock is housed in Besançon Cathedral. Auguste-Lucien Vérité of Beauvais designed and built Besançon's present astronomical clock, between 1858 and 1863. It replaced an earlier clock that Bernardin had constructed in the 1850s that proved unsatisfactory. Besançon's clock differs from those in Strasbourg, Lyon, and Beauvais. The clock is meant to express the theological concept that each second of the day the Resurrection of Christ transforms the existence of man and of the world.
