£800,000 Conservation Project Begins at Stourhead’s Historic Dam
The National Trust has launched a critical £800,000 conservation project to preserve the 18th-century dam at Stourhead, a world-renowned landscape garden in Wiltshire. The work aims to safeguard the structural integrity of the dam, which forms the centerpiece of Henry Hoare’s iconic “Paradise Valley” design.
A Masterpiece Under Pressure
Built over 275 years ago, the dam was engineered to flood the valley and create Stourhead’s 178,000m³ man-made lake—a volume equivalent to more than 70 Olympic swimming pools. Recent monitoring revealed increasing water seepage through the embankment, prompting urgent repairs to prevent long-term damage.
Engineering Meets Heritage
Specialist contractors are installing 4.5-meter-long steel piles across a 50-meter section of the 220-meter dam. This intervention addresses modern challenges while respecting the site’s Georgian heritage. Nigel Hellier, National Trust Project Manager, emphasized the dam’s critical role: “The lake is the heart of Stourhead’s design. These repairs ensure future generations can experience this historic landscape as intended.”

Visitor Experience During Works
While a small lakeside path near the dam remains closed, most garden routes stay accessible. Two new walking trails—Aeneas’s Walk (featuring the Temple of Flora and Pantheon) and Apollo’s Walk—offer alternative perspectives. The house remains open for booked tours, with discounted £15 entry for non-members during repairs. Work is expected to conclude before Easter 2024.
Expert Perspectives on Preservation
Tim Parker, Head Gardener at Stourhead, described the lake as “Henry Hoare’s final, most impactful stroke on his living artwork.” He added: “This project ensures the dam functions for centuries to come, maintaining a pinnacle of Georgian landscape design.”

Philip Niemand, General Manager for the National Trust, highlighted the broader significance: “This investment isn’t just about repairs—it’s about protecting a national treasure. Visitors can now witness conservation in action, understanding the expertise required to preserve such landscapes.”
A Legacy Secured
As one of Britain’s most visited heritage sites, Stourhead’s dam project underscores the National Trust’s commitment to blending historical preservation with modern engineering. With its lake secured, Hoare’s 18th-century vision will continue to inspire visitors amid Wiltshire’s rolling hills.
