Wilderness gardens were created in deliberate contrast to the rigid formality of gardens immediately surrounding country houses. Clumps of shrubs, specimen trees, meandering paths and the dappled sunlight of surrounding woodland created a romantic illusion of an untamed landscape, in which people could walk and experience nature.
This part of the estate also contains a large boulder, about a metre across, that is composed of hundreds of fossilised oysters, and has been dated back to around 165 million years ago. I didn't take a picture of it, as its picturesque interest is of a somewhat limited value.
