Context
About 1,750 years. The stone circle went up around 2500 BC; tradition puts the founding of Rome at 753 BC. The stones were already ancient before there was a Rome.
For scale, Rome's founding is about 2,780 years before today, so Stonehenge was nearly as old to the first Romans as the first Romans are to us. The dates come from English Heritage and the traditional Roman chronology, and both carry some uncertainty.
