Architecture was built during the roman era?

Most Roman triumphal arches were built during the imperial period. By the fourth century AD there were 36 such arches in Rome, of which three have survived – the Arch of Titus (AD 81), the Arch of Septimius Severus (203–205) and the Arch of Constantine (312). Numerous arches were built elsewhere in the Roman Empire. hope this helps.
