This is the Palais de Justice in Montpellier. It was built around 1850. It is a very beautiful building, which is located on the avenue Foch, close to the Arc de Triomphe and to the Esplanade du Peyrou.
Photo taken from the top of the Arc de Triomphe, which I will show in the next days. The Avenue Foch is probably the wealthiest street in Montpellier, with some of the best and the most expensive "boutiques" in the city.
