Of fact, Rome is still being constructed, and it has gone through cycles of development and demolition since its establishment in 753 BCE. The city now comprises a number of distinct neighborhoods including Ancient Rome, a name given to the series of monuments dating from about 500 BCE to 150 CE; Central Rome, which includes Trajan's Market and the Spanish Steps; and Near North Rome, home to many modern-day apartment buildings. Rome has been described as a living museum because many of its ancient structures are maintained by local governments or private organizations that charge admission fees. Visitors can explore several imperial palaces and museums built after the destruction of much of the old city center during World War II. Others worth seeing include the Vatican Museums (with their famous Sistine Chapel) and the Roman Forum. The Eternal City was originally inhabited by early humans around 200,000 years ago, but it wasn't until about 5,000 years ago that humans started to build cities here. The Etruscans were the first civilization to establish themselves in Rome, but they were eventually replaced by the Romans. In 509 BCE, the city was officially made capital of the newly formed Roman Republic.
