In 210 BC, at the end of a heavy siege, Akragas was conquered by the Romans. It took the name of Agrigentum, and from the end of the second century BC received some important public works, particularly in the central area of the city. From an urban point of view, these served to show that the city belonged to the Roman Empire. Among these, perhaps the most significant and best known from an archaeological point of view is a small temple on a podium, Roman-style, on the hill of San Nicola, which rose in the centre of a large colonnaded square. Although at this time it was no longer counted among the most important in Sicily, the city enjoyed a remarkable affluence, which can be seen by visiting the houses that occupy the three residential blocks highlighted in the 'Hellenistic-Roman Quarter' many of which are large, monumental and richly decorated. The prosperity of the city depended largely on resources that were produced in its hinterland, mainly agricultural products, grain, oil and wine, and the sulphur extracted in the mines of its territories. From the end of the fourth century AD, as in many cities in the empire, a profound transformation of the urban landscape began in Agrigentum which, over several decades, greatly changed the face of the city.
