Stonehenge was built in several stages between about 3000 and 1520 BCE, with work starting roughly 5,000 years ago in the late Neolithic and continuing into the early Bronze Age.

Quick Scoop: Timeline in plain terms

  • The earliest earthwork enclosure at Stonehenge dates to around 3100–3000 BCE, marking the first major construction phase.
  • The iconic large sarsen stone circle and trilithons were erected roughly between 2600 and 2400 BCE.
  • The smaller bluestones were set and rearranged multiple times, with key phases around 2400–2200 BCE and further adjustments into the mid‑2nd millennium BCE.
  • Overall, archaeologists describe Stonehenge as having been built and modified in several stages from about 3000 to 1520 BCE.

Why the dates vary

  • Different sources often round the construction span to “between 3000 BC and 2000 BC” or “about 5,000 years ago” because the building happened in multiple phases and the dates come from radiocarbon and soil analysis, which have ranges rather than exact years.
  • Modern estimates align that the main visible stone monument took shape in the 3rd millennium BCE, while earlier use of the site and later alterations stretch the overall timeline on both ends.
