Rome, the "Eternal City," has been a sacred place and internationally important city since ancient times. Rome's history extends nearly 2,800 years, during which time it has been the seat of the Roman Kingdom, the Roman Republic, the Roman Empire, the Papal States, the Kingdom of Italy and the Italian Republic. The first known temple in Rome was built around 575 BC. A Jewish community was established in Rome in 161 BC and remains active today. Christians arrived in the 1st century AD, and Rome has been the center of Catholic Christianity ever since. Rome's abundance of ancient temples, synagogues, churches and shrines make it one of the best cities to explore the holy places of a variety of religious traditions.
This magnificent ancient temple was built by Emperor Hadrian in 125 AD and converted into a church in 609. It is the oldest intact ancient building in Rome.
