Once home to the city's archbishops, this sprawling edifice looms up at the center of the old town. It's mainly worth visiting for the chance to climb up to the top of the keep for fabulous views across the countryside around Narbonne. Outside on place de l'Hôtel de Ville, look out for a preserved section of the Via Domitia, the Roman road which once ran right across Gallia Narbonensis, all the way from Rome to Spain.
The palace also houses several archaeological museums, although the collections will change after the opening of NarboVia. Most interesting is the Horreum, with an underground gallery of Gallo-Roman shops.
