The lapidary museum contains 1,300 antique writings, steles, lintels, busts, sarcophaguses, and enormous sculpted blocks. Most of the items come from the ramparts of the walled town and show the prestigious past of the former capital of Gaul in Narbonne. Everything is housed in a proud-looking converted church, Notre-Dame-de-la-Mourguié.

The terrace standing next to the cathedral gives an interesting view over the region ( (the Orb, the Canal du Midi snaking among the vineyards, the Cévennes ridge and the Espinouse mountans).

The Archaeological Museum contains prehistoric artefacts and the first tools from the Bronze Age. There are reconstructions of Roman Narbonne through its institutions, daily and religious life and its myths. What makes the museum stand out, though, is its wonderful collection of Roman paintings from the archaeological site of Clos de la Lombarde, which used to decorate the villas of the rich of Narbonne and are unique in France!

Situated within the cemetery, this former parish church, built of pink sandstone, dates from the first half of the 12C. Outside, note the elegant east end decorated with Lombard arcades, and the archaic sculpted figure. The lintel of the south doorway features Christ's monogram spelled in Arabic script and blossoming into a crucifix. The interior contains Mozarabic capitals and two 12C low-reliefs by the Toulouse School: a face of Christ in Majesty and a St Peter.
