Located at the top of the hill overlooking the Loire, between the cathedral and the ducal palace, the Town Hall is the center of a monumental space where spiritual and temporal powers are present since the Middle Ages. The great architectural homogeneity of this neo-classical building hardly suggests that it is the result of a century of development. The central part was built around 1830 to house the library, the justice of peace and the commercial court. A second phase of work was carried out between 1847 and 1850 to house the museum. The municipal administration then decided to settle there, which led to an expansion at both ends between 1850 and 1865\. Finally, a reception room was built in 1899, whose gilding now houses the offices of civil status.
