The Hotel de Ville, like most older fine buildings in Bordeaux, was built in the 18C as a palace for the Archbishop (Prince Rohan) which is why it is next to the Cathedral. The preferred view is from the garden behind it which we did not take. On the next street North is the Musee des Arts Decoratifs (we did not visit it). Off the garden, also North, is the Musee des Beaux Arts (See Our Tips). To tour the magnificantly decorated interior of the Hotel de Ville you must be available on Friday afternoon (we were not there then).
Built for the Archbishop of Bordeaux in 1771, the palace of Rohan features a grand staircase and an intricately decorated dining room.
