Septimontium
The Septimontium was a festival celebrated by the montani, residents of the seven hills associated with Rome. These hills were Oppius, Palatium, Velia, Fagutal, Cermalus, Caelius, and Cispius.
Date: 11th December
The festival was held in September or, according to later calendars, on 11th December. During the Septimontium, Romans refrained from using horse-drawn vehicles.
The Septimontium was a way for the residents of the seven hills to come together and celebrate their shared identity. The festival was a reminder of the importance of unity and cooperation among the different communities that made up Rome.
