Bab Caracalla, or as it is called the Arch of Caracalla, is one of the most impressive and largest monuments in Tebessa, which is considered a wonderful and unique architectural masterpiece, one of the best that the Romans built in the city. The door has four sides decorated and polished, each side dedicated to a member of the ruling family at the time. Despite the succession of civilizations on the city, it is still steadfast to this day, and some restorations and repairs have been made recently.
