"Cathedrale St. Jean & Horloge Astronomique" Besançon Things to Do Tip by smirnofforiginal

Cathedrale St. Jean is predominantly 18th cntury. It sits just below the citadel on Rue de la Convention and houses the Horloge Astronomique (clock) which has 300 moving parts inside it.

There are 7 guided tours, daily. We opened a door and went inside... not realising that we were actually sneaking in because we were not on one of these tours and neither had we paid!
