The old palace of the archbishops, which distinguish itself by several towers (donjon Gilles Aycelin (End of 13th – beginning of 14th century), tower Saint Martial and of the Madeleine (13th century)), includes the “Palais Vieux” of Romanesque origin and the “Palais Neuf” of Gothic style modified during the 12th and 13th centuries. It accommodates since the 19th century the Town Hall, the Museum of Art (old apartments), the Archaeological Museum (wing of the Old palate). It leans on the first enclosure of Narbonne, and the archbishop's garden extends on its backside.
