Eastern Walled Kitchen Garden

The Eastern Walled Kitchen Garden is an 18th-century structure, likely dating to around 1751, although a slate plaque incorrectly attributes its creation to Sir John Wynn in 1761; it was actually Sir Thomas Wynn who held the baronetcy at that time. Originally divided into four unequal sections, with the southern sections being larger, the garden walls are constructed of rubble on the outer face and English garden-wall bond red brick on the inner face, topped with slate coping. The walls are approximately 3 meters high, with indications that they have been heightened on the north side.

On the west side, the wall adjoins modern machinery workshops and includes a brick pointed arch with a boarded gate. A small round arched doorway with a stone surround is located near the north end, with a blocked opening almost at the corner with the north side. The remains of a boiler house, retaining its red brick chimney stack, stand against the north side of the garden. At the north-east corner is a derelict area featuring three pointed arches, the central one being tall and designed for cart access, surmounted by a plaque inscribed "Victoria Jubilee 1897." The wall runs down the east side, roughly parallel to a farm track.

The south end wall runs parallel to the cold frames behind the main complex and faces a small gardeners’ cottage, bearing an inscribed slate plaque reading "This walled garden was made by Sir John Wynn Bart in the year 1761.” A Peach House is situated against the north wall, restored in 1991, with a lean-to Plum House attached to its left. Further south is a melon pit, with renewed woodwork and glass, but retaining original ironwork, pipework, slate flooring, and humidity trays for the hot pipes; it was designed by Foster and Pearson. A sundial has been relocated from its original central position.

A former underground tunnel linked the kitchen garden to a neighboring garden to the west. The tunnel entrance, located midway along the west side, is under a segmental brick arch with voussoirs and arch ring. The tunnel is segmental vaulted and faced in yellow brick, turning at a right angle to the south before ascending into the next garden.
