The gate was inscribed with the name of the colony, 'Colonia Augusta Nemausus', to honor Emperor Augustus.
It originally stood as part of a circuit of walls that enclosed 220 hectares of Roman urban territory.
The central arches allowed for the passage of heavy carts, maintaining the logistical flow of the Via Domitia.
The masonry technique used here, known as 'opus quadratum', involves dry-laid, large blocks without mortar.
The structure survived centuries of urbanization due to the ongoing strategic importance of the road path it guarded.
The Porte d'Auguste, also known as the Porte d'Arles, served as the primary entrance to Roman Nîmes, then called Nemausus, along the Via Domitia. Constructed around 16 BC, it remains one of the few surviving sections of the city's original 6-kilometer-long Augustan defensive wall. The structure features four arched openings: two large central bays for wheeled traffic and two smaller side arches for pedestrians. Architecturally, it is defined by its massive stone masonry and remains a key vestige of the Roman urban fortification system. It was strategically located at the intersection of the main road connecting Italy to Spain. Today, the monument sits integrated within the modern streetscape of Nîmes, specifically at the end of the Boulevard Amiral Courbet. Archaeological excavations have identified that the gate was once flanked by two semi-circular towers for enhanced defense. It serves as a testament to the monumental building program initiated under Emperor Augustus.

Do not treat it as a building to enter; it is an open-air public monument to be viewed from the street.
