The Vestiges of the Gallo-Roman wall are the remains of a fortification built in Grenoble (ancient Cularo) at the end of the 3rd century under Emperors Diocletian and Maximian, when the city gained Civitas status as an administrative capital of the Roman Empire [1]. The wall originally spanned 1,150 meters and enclosed a 9-hectare Roman settlement, featuring 39 semi-circular watchtowers each 7.5 meters in diameter [1]. Constructed of limestone blocks, pebbles, and tuileau rubble with mortar, some sections reached 4 meters thick; two monumental gates bore inscriptions naming the emperors [1]. The wall symbolized Cularo's elevated status within the empire [1].
