Important city of Roman Spain, later capital of the province of Hispania Tarraconensis, with the first identifiable occupation by the local Iberian. In 218 BC, it was captured by Roman generals and was transformed into one of the earliest Roman strongholds in Spain. Augustus recuperated there during his Cantabrian wars, where an altar and temple were later dedicated to him. The emperors Hadrian and Trajan endowed Tarragona with power and cultural prestige, while its flax trade and other industries made it one of the richest seaports of the Roman Empire. It prospered until being sacked by the Franks in 260 AD. Remains surviving include the Republican-period walling, Augustus' palace, an amphitheater, a section of aqueduct (the Devil's Bridge), and a Romano-Christian cemetery.
