The working city of Narbonne is situated at the junction of the sea and river. It became a harbour city under the Roman Empire. From the twelfth to the fifteenth centuries, Narbonne grew and became a brilliant centre of Gothic art. Many monuments and buildings such as the Old Bridge, the Horrea (Roman warehouses), the Via Domitia, the palace of the Archbishops, the cathedral St Just and St Pasteur are all remarkable remains of these periods of economic prosperity. The Canal de la Robine’s inviting banks is a great place to cycle, take a stroll or sail at the junction of the Canal du Midi.
