While you will typically find GPR surveys used on construction sites to source utility pipes and cables below ground prior to building, there are a host of other uses for the technology. In July 2021, for instance, a volunteer research group employed a GPR survey on a golf course in Thurrock, Essex, to discover the remains of gardens dating back to Tudor and Jacobean times beneath the surface. With the assistance of expert GPR surveyors, they were able to find stronger evidence of the layout of the former gardens.
Historic England’s senior
geophysicist, Neil Linford, explained that previously taken aerial photos of
the site, Belhus Park Golf Course, had indicated the outline of a garden that
appeared similar in form to pictorial representations of the estate from the 17th and 18th centuries.
These suggested the
survival of the layout of the old garden. It was the volunteers of local
conservation group Land of The Fanns who first noticed that the aerial photos
resembled a bird’s eye view painting of the manor, and a further non-invasive
study of the area has now confirmed this discovery.
The GPR survey
findings included a circular water feature to the west of the former manor
house, which can be seen in a painting from around 1710 that depicted the
gardens. The manor was one of the most prominent houses in England in the 14th
century and was inhabited for centuries. However, it was damaged by bombing
during World War II and was finally demolished in 1957.
It’s known that, during the mid-18th century, renowned landscape
architect Lancelot ‘Capability’ Brown replaced the original Tudor gardens with
a new design. Capability Brown, of course, worked on hundreds of gardens in his
time, including those at Blenheim Palace, Chatsworth House and Hampton Court,
and around 150 of his works have survived into the 21st century.
Historic England’s goal is to
preserve this historical setting and have Belhus Park removed from the Heritage
at Risk Register.
The organisation’s landscape
architect, Christopher Laine, said they already knew that Belhus Park was
something special, which is what prompted them to survey the land with GPR.
According to Laine, the discovery
of this former Tudor Garden will provide the information the body needs to
improve the conservation and management of this important heritage site,
benefitting the current and future generations.
Karl Hayes, managing director of
Belhus Park golf course, said the project had the golf club’s complete support
and he is looking forward to the club’s role in exploring, understanding, and
preserving the findings.
This discovery shows the value of
GPR in uncovering the history that lies beneath the ground and cannot easily be
seen by any other means. Historic England said it is hoping there will be
further opportunities at Belhus Park in the future for volunteering, engaging
with the community, and exploring this great new resource.
