You’re now in Saint-Jean Square, facing the Hôtel-Dieu of Guérande, a true historic landmark whose exact construction date is still unknown. Step a little closer and you can see its façade on the left. This was once a religious hospital run by clergy, offering care and shelter to the sick, the poor, and passing pilgrims. As was customary for such institutions, it originally had a chapel right next door, which has since disappeared, though the main hospital building remains. Its preserved architecture gives you a real sense of stepping back in time. In 1796, it was sold to the state and converted into a military hospital. By the mid-19th century, a new hospital was built nearby, and the old Hôtel-Dieu was transformed into a school for a while. Today, after restoration, the building houses offices and is occasionally used to host exhibitions and other cultural events.
