Stonehenge

From the shuttle stop the stones look smaller than you expect against the wide plain, but as you walk the circular path around them the scale and the weight of the sarsens become clear.

The lintels balanced across the uprights are what set Stonehenge apart, and the careful way the ring was built keeps drawing the eye around its broken circle.

The setting is pure open grassland and sky, with barrows and ancient earthworks scattered across the plain around the monument.

You cannot normally walk among the stones on a standard ticket, so the visit is a slow circuit at a respectful distance rather than a close scramble.

The larger sarsens, each weighing up to 25 tonnes, were sourced from the Marlborough Downs 25 miles north, while the smaller bluestones came from the Preseli Hills in Wales, 150 miles away — a logistical achievement whose methods archaeologists still debate.

No mortar was used in Stonehenge's construction; the stones were shaped by some unknown combination of hammering, pecking and abrasion, then fitted together using mortise-and-tenon joints and stone pins in a technique that demonstrates considerable masonry skill.

It is the most famous prehistoric monument in Europe and a genuine feat of Neolithic and Bronze Age engineering that still resists full explanation.

Standing before stones raised thousands of years ago, aligned to the movements of the sun, is a direct and surprisingly moving link to deep prehistory.

The surrounding landscape of barrows and avenues shows that the ring was the centre of a much larger ancient ritual world, not an isolated object.

Stonehenge was constructed in stages between roughly 3000 and 2000 BC, its massive sarsens and smaller bluestones arranged in a deliberate pattern whose precise solstice alignments suggest an astronomical purpose that modern archaeology has yet to fully explain.
