 Auguste Audollent divides the area of Roman Carthage into four quarters, "Cartagenna", "Dermèche", "Byrsa" and "La Malga".Cartagenna and Dermèche correspond with the lower city, including the site of Punic Carthage; Byrsa is associated with the upper city, which in Punic times was a walled citadel above the harbour; and "La Malga" is linked with the more remote parts of the upper city in Roman times.French-led excavations at Carthage began in 1921, and from 1923 reported finds of a large quantity of urns containing a mixture of animal and children's bones.
