Stonehenge marks 40 years as UNESCO World Heritage Site

Stonehenge is approaching its 40th anniversary as a UNESCO World Heritage Site this November. Since its inscription in 1986, the number of World Heritage properties in the United Kingdom has grown fivefold, increasing from seven to 35.

Heritage sites remain central to the British visitor economy. According to a 2024 VisitEngland survey, four of England’s six most visited paid attractions are located within World Heritage properties, with Stonehenge ranking sixth.

Recent archaeological research is also providing new insights into the monument's origins. Modern scientific methods, including isotopic analysis and acoustic modeling, suggest the site was a sophisticated multigenerational project led by Neolithic farmers, artisans, and spiritual leaders between 3000 BC and 1500 BC.
