Porte Noire

Porte Noire is a Roman arch in Besançon standing roughly 16 meters (54 feet) high and 2 meters (6.5 feet) deep, decorated with weathered stone carvings across multiple tiers. The structure displays mythological reliefs carved into pale limestone that once served a ceremonial purpose.

The arch was built between 171 and 175 AD during the reign of Emperor Marcus Aurelius. Later, as the empire faced external threats, the structure was repurposed from a ceremonial entry into a functional defensive element for the city.

The carved reliefs feature figures from Greek and Roman mythology, including the Dioscuri, Daedalus, Icarus, and Theseus. Visitors can still observe these mythological characters in the stone today, reflecting how classical stories were woven into everyday city life.

The arch sits on Rue de la Convention in the city center and remains accessible throughout the year. Visiting in early morning hours allows you to study the carved details with fewer crowds around.

Hidden chambers were discovered beneath the stone surface during archaeological investigations. These voids reveal details about how Roman builders engineered such structures internally.
