The older settlement was overbuilt in the II-I c. BC by that identified with the repopulation of the colony at the end of the First Servile War in 132 BC. The organisation of the city with a grid of insulae framed by north–south and east–west roads follows the pattern of the previous phase. The houses typically consist of two or more rooms surrounding a courtyard with a hearth. The house walls are built on a base of chalk stone blocks with mud bricks above.
