Besançon, the former French capital of watchmaking and today at the forefront of time measurement, invites you to enjoy a unique experience: explore the various components and dimensions of time... in 24 hours! Find the whole program on www.les24hdutemps.fr.
To accompany this event, Besançon Ville d'Art et d'Histoire and the Tourist Office of Greater Besançon offer you visits around Time
A meridian telescope is an astronomical telescope whose movements are limited to the meridian plane, a vertical plane oriented north-south.
By observing the moment of passage of a star on the meridian, whose position is known, we can make time, that is to say correct the time of a clock (if the star passes too early in the field of the telescope it is that the clock is delayed, if the star passes too late it is that the clock advances).
