Dominating the North Garden is the Victorian Parterre, which was restored in 1996, in a Union Jack pattern of triangular beds, edged with box and planted with colourful seasonal bedding and evergreen euonymus. The parterre is divided from the north parkland by a row of topiary yews.

The parterre was re-discovered when the outline of the beds could be seen in the snow one winter.  After archaeological excavations the flower beds were cut into the lawn and then edged with thousands of box plants.

The pair of giant stone vases on the park boundary fence are carved with goats’ masks and the pipes of pan date to the nineteenth century, but a series of lead urns on either side may be survivors form Radnor’s original formal garden. The great east and west avenues, which continue the line of the path parallel with the railings, were laid out in the 1690's, and can be seen both in Kip's engraving of the house and gardens and in Bridgeman's preliminary survey drawings - although largely replanted at later dates.
