The Stonehenge Landscape is one of the most important prehistoric landscapes in Europe. We care for over 2,100 acres (800 hectares) of the World Heritage Site and take our responsibility to protect it seriously. Understand our position on the Government’s plan to invest in a two-mile tunnel, removing a part of the existing A303 which is damaging the landscape.

The benefits of a tunnel on the A303

The current A303 cuts through the heart of the World Heritage Site, harming the setting of many of the 400 sites and monuments scattered across the landscape. It divides the Stonehenge Landscape, cutting off the southern two thirds for visitors and wildlife alike. For most people, visiting the stones is associated with traffic jams, HGVs and the drone of vehicle engines.

If designed and delivered with care, a tunnel will finally reunite this prehistoric landscape, protecting the special qualities of the World Heritage Site, reconnecting habitats and helping people to discover and enjoy more of the landscape.

The removal of the road will ensure future generations will be able to experience the stones and monuments in a setting more familiar to their builders. This ancient place will finally have the future it deserves.

Working with our partners

We continue to believe in the long-term benefits of the proposed road scheme for people, history and wildlife and are working closely with our partners, Historic England and English Heritage, to help inform and challenge National Highways to deliver a scheme that protects the special qualities of the Stonehenge World Heritage Site and finally addresses the major harm the existing A303 does to this special place.
