Prince Charles was given a tour of Kirkharle Courtyard and the nearby lake yesterday.
It was part of a two-day visit to Northumberland, which continues today.
This includes attending the Duchess of Northumberland’s annual garden party for volunteers and carers in Alnwick.
At Kirkharle, The Prince of Wales attended a reception for beneficiaries and supporters of the Upper Teesdale Agricultural Support Services group, which is marking its 25th anniversary.
Lancelot ‘Capability’ Brown, described as England’s greatest landscape designer, was born and grew up in the village of Kirkharle.
From 1732, he worked at the Kirkharle estate, then owned by Sir William Loraine, the 2nd Baronet, learning many skills in gardening, planting and land reclamation.
Brown produced a plan for him to replace the early 18th Century formal gardens with a more naturalistic landscape, but his design was only partially implemented at the time.
Over the past 10 years, the owners of Kirkharle Courtyard have been implementing the long-forgotten Capability Brown plan that they re-discovered in 1980.
The work carried out in 2016 to celebrate the tercentenary of his birth and baptism in Kirkharle included installing wooden edging round the lake and excavation at both ends to give the illusion of a river flowing through the landscape.
