Evidence of human activity around Stonehenge reaches back to about 8000 BC, but the monument itself began around 3000 BC with a circular ditch and embankment. Standing timbers were erected first. From approximately 2500 BC, the great project of transporting and raising stones began. The bluestones arrived first, followed by the enormous sarsens that form the iconic trilithons, pairs of uprights capped by horizontal lintels. Construction was not completed until roughly 1600 BC. Each generation built upon its predecessors' work, a continuity of purpose spanning sixty generations that suggests Stonehenge held a significance deeper than any single community's beliefs. The site received UNESCO World Heritage status in 1986.

The alignment of Stonehenge with the summer solstice sunrise and winter solstice sunset has been recognized since the eighteenth century. On the longest day of the year, the sun rises over the Heel Stone and its light penetrates the heart of the monument. This is not accident. The Avenue, the ceremonial approach to the stones, follows this same solstitial axis. But Stonehenge was more than a calendar. Current research suggests it served as a place of the dead, complementing the timber monuments at nearby Durrington Walls and Woodhenge, which appear to have been settlements for the living. The distinction between stone and wood, between the permanent dead and the temporary living, may have been central to Neolithic belief on Salisbury Plain.

The Stonehenge landscape is not just archaeological but ecological. The chalk grassland surrounding the stones is one of the best-preserved areas of accessible downland in Britain. Thin, free-draining soil supports an unusually diverse range of plants and insects. The rare Chalkhill Blue and Adonis Blue butterflies breed here, and skylarks nest in such numbers that the nearby military garrison is named Larkhill. The Royal Society for the Protection of Birds maintains a reserve on Normanton Down for the Stone Curlew. An ongoing chalk grassland reversion project, one of Europe's largest, is converting hundreds of hectares of former farmland back to pasture, gradually restoring the landscape to something closer to what the monument's builders would have known.

Stonehenge becomes a different place at the solstices. On the summer solstice, English Heritage opens the monument for free, and thousands gather in the predawn darkness, druids in white robes alongside tourists with smartphones, all waiting for the sun to clear the horizon. The winter solstice draws smaller but equally devoted crowds. At the equinoxes, similar gatherings mark the turning of the seasons. These modern ceremonies have no documented connection to prehistoric practice, but they serve as evidence that the stones still exert a gravitational pull on human imagination. The rest of the year, visitors follow roped pathways around the monument with audio guides, though early-morning and evening access can be arranged for those who want to walk among the stones themselves.

The temptation is to see the stones and leave. Resist it. The wider landscape contains monuments that are equally important and far less crowded. Woodhenge, two miles to the northeast, is marked by concrete posts where massive timber uprights once stood. The Stonehenge Cursus, a mysterious earthwork nearly two miles long, is older than the stone circle. Durrington Walls, the largest known henge enclosure in Britain, was likely a settlement that housed the workers and celebrants who gathered at Stonehenge. Barrow cemeteries line the ridges, and the whole landscape can be explored on foot through paths the National Trust has opened across its land. From the air, the relationships between these sites become startlingly clear, an entire sacred landscape laid out across the rolling chalk.
