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.

A beautiful local recreation area for hiking, swimming, and other recreational activities. The path around the lake is more suitable for hiking than cycling. We still managed it, though.
