It was once the economic and political center of the Roman Empire. It has a history of more than 2,000 years. Most of the interior buildings were ruins. Scenic spots include temples, Arc de Triomphe, the Presbyterian Church and other buildings, with exquisite structure and magnificent momentum, reminiscent of the glory of Rome in the past. There is hardly any shade in the ruins, and the light is intense. It's best to go early in the morning or at dusk in summer.
