The temporary emporium settlement gave way to an articulated district of warehouses and houses, served by a straight road axis, which was evidently designed according to functionality and modularity criteria typical of an advanced urban planning. In the same period the city, whose port became the center of important trade routes, experienced a significant development of its monumental endowment, with the construction of a temple near the warehouses themselves and other sacred areas in correspondence with the three main hills of the peninsula: the so-called ‘Temple of Tanit’, the sacred area of Coltellazzo and that of Sa Punta ‘e su Coloru (on which the Sanctuary of Aesculapius would later rise, a place where some interesting terracotta statues depicting devotees of the salutary divinity were found). Over time the inhabited area expanded towards the west, with the progressive development of new residential and artisan districts in the direction of the ancient port inlet, now partly occupied by the fishpond behind the peninsula of Is Fradis Minoris.
The simultaneous development of the chamber necropolis in the isthmus area and the tophet in the suburban sector, but also the intensive use of the quarries of the nearby peninsula of Is Fradis Minoris, confirm the importance assumed by Nora in the Punic age up to the initial stages. of the Roman domination.
