Step off the noisy streets and into a soothing house of prayer at Cathédrale St-Jean. You can indulge in a few moments of self-reflection here.
When you've spent some time at this Besancon Old Town principal church, why not check out Besancon Citadel, University of Franche-Comte, and Micropolis Conference Center? They're not far from Cathédrale St-Jean and also a hit with travelers.
