Within the Gaul of Narbonne, the Vocontii people signed a friendship treaty with Rome, which gave them some autonomy. The city was governed by two capitals: Vaison-la-Romaine and Luc-en-Diois.
Under the circumstances that are not well known to this day, this large territory explodes into four autonomous cities. Vaison, Gap and Sisteron therefore run their own city. In the Diois, Lucus Augusti Vocontiorum (Luc-en-Diois) leaves the place of capital to Dea Augusta Vocontiorum (Die).
The city grows and usual elements of a Roman capital appear within it: a forum, temples, two aqueducts, public and private thermae for instance. Dea Augusta Vocontiorum is an important sanctuary of the cult of Cybele (Great mother), before getting the status of Roman colony, and surrounding itself with a rampart.
Today, Die contains one of the three biggest lapidarium collections in Rhône-Alpes (along with Lyon and Vienne). The rampart and the famous gate of Saint-Marcel are listed as historical monuments. In our museum you can immerse yourself in the city's Roman sumptuous past thanks to the big rooms of gallo-roman lapidarium collection!
