The Laurentine Gate belongs to the city walls of the first century BC. It received its modern name from the village Vicus Augustanus Laurentium, a small settlement a few kilometres to the south of Ostia. Beyond the gate was a huge necropolis, starting at a distance of c. 50 metres. The gate was excavated in 1938-1942.
