Stonehenge’s main building was largely complete by about 2500 BC—not 1,500 years. Phase 1 (c. 3000 BC): an early henge with timber posts, bluestones and cremation burials. Phase 2 (c. 2900–2600 BC): the Preseli bluestones, from more than 200 miles away, were rearranged. Phase 3 (c. 2600–2500 BC): monumental sarsen trilithons and the stone circle. The Avenue followed c. 2400 BC, with major rearrangements to c. 2300 BC. Stonehenge remains a chronological marker for Neolithic Britain. 🪨
