According to legend, the Carthaginian Hamilcar Barca, Hannibal's father, founded the city of Barcelona. However, the existence of a Carthaginian Barcelona has never been proven. Therefore, it is likely that the first inhabitants of Barcino (Latin name of modern Barcelona), founded around 300 BCE, were people of Iberian origin.
Later, the Romans reorganised the town as a Castrum (a military camp), located on Mount Tàber, a hill where the town hall and the seat of the Generalitat de Catalunya (Plaça de Sant Jaume) stand today. The Romans baptised the city as Colonia Iulia Augusta Faventia Paterna Barcino. The ancient organisation of the streets is still visible in the maps of the old town and in the Roman walls that have remained standing. It is believed that Barcino also had an amphitheatre near the Basilica of Santa Maria del Mar.
