I visited Lanhydrock House as part of a tour of Cornish gardens in July 2010. The house is grade 1 listed and owned by the National trust. A formal garden is laid out in front of the house with large topiary punctuating the parterres. To the rear of the house a more rambling garden is planted with rare trees and shrubs. This 1,000 acre property of wooded parkland includes 30 acres of woodland and tree lined avenues.
