Until the mid-19th century, the remains of a Gallo-Roman arch, which marked the northern city limit, were still visible. After being integrated into the fortifications at the end of the 3rd century and becoming a city gate, this structure owes its name either to its length or to a legendary king named Longo, whose effigy was mounted on a corbel overlooking the city. Around 1538, a barbican was built in front of the gate to prevent a frontal assault.

Nice hike with parking and picnic area nearby. The path leading to the spring is a bit steep and can be slippery if it rains. The Sabinus cave is worth the detour, watch out for children when going there.

The Marne (Latin Matrona) is a river in France. It rises on the plateau of Langres, in the municipality of Balesmes-sur-Marne, at an altitude of about 420 meters. It initially drains to the northwest, later turns to the west and southwest and flows into the Seine as a right tributary after about 514 kilometers between Charenton-le-Pont and Ivry-sur-Seine, just southeast of Paris. Several French departments are named after the Marne, namely Haute-Marne, Marne, Seine-et-Marne and Val-de-Marne.
