Italica was the birthplace of the Roman Emperors Trajan and Hadrian. Hadrian's generosity to his home town, which he made a Colonia, added temples, including a Trajaneum venerating Trajan, and he rebuilt public buildings. Italica’s amphitheater seated 25,000 spectators-half as many as the Flavian Amphitheatre in Rome- and was the third largest in the Roman Empire. The city's Roman population is estimated at 8000. The games and theatrical performances funded by the local aristocracy, who filled the positions of magistrate, were a means of establishing status: the size of the amphitheater shows that the local elite was maintaining status far beyond Italica itself.
The modern town of Santiponce overlies the "old city" of Republican times founded by Scipio and pre-Roman Iberian city. The well-preserved city is the nova urbs magnificently laid out under Hadrian's patronage.
A shift of the Guadalquivir in its bed, probably as a result of siltation- a widespread problem in Antiquity that followed removal of the forest cover-left Italica isolated, high and dry. The city started to dwindle as early as the 3rd century. Later Seville grew nearby, and no modern city covered most of Italica's foundations. The result is an unusually well-preserved Roman city of Hispania Baetica, and unexpected riches in the Museo Arqueologico of Seville, with its famous marble colossus of Trajan. In Italica, cobbled Roman streets are visible, and mosaic floors still in situ. The excavation of Italica began in 1781 and continues.
