I want to know the answer to the following question:
What did the city hall used to be known as?
All the background I'm provided with is that "Other buildings of its kind are the "Hôtel de Hanau" (1736, now the city hall), the Hôtel de Klinglin (1736, now residence of the préfet), the Hôtel des Deux-Ponts (1755, now residence of the military governor), the Hôtel d'Andlau-Klinglin (1725, now seat of the administration of the Port autonome de Strasbourg) etc.". Is that enough to answer the question?
Answer: yes
