Brindisi has one of the longest roads in Italy that connects it to Rome, it's called Via Appia and it's a unesco heritage. This road was made because Brindisi has one of the best ports in Europe and in Italy so the Romans needed an efficient way to travel there so Brindisi is a pretty old city but for some reason is still small and unknown for some Italians
