Walls and Steps retaining Upper (house) Terrace and retaining Walls and Steps to Rose Terrace

The walls and steps retaining the Upper Terrace and the Rose Terrace are 18th-century structures. The upper terrace walls are approximately 1.8 meters high, constructed of random rubble with a slight batter and topped with moulded sandstone copings. Sandstone steps lead down to the Rose Terrace from both the northern and southern ends of the west side; the northern end features a single flight of 14 steps, while the southern end has two staged flights with 7 and 8 steps, respectively, and coped parapets at the southern end. Decorative stone lions, sphinxes, and flaming urns are placed at intervals along the walls, predominantly the urns. The terrace walls return eastward at both ends to align with the house. On the southern side, there is an additional centrally-placed two-stage flight of steps. The terrace extends for about 30 meters before curving back to the south to frame the front lawns.

The Rose Terrace is paved with Yorkstone flags and features a central astrolabe on a baroque stone plinth. At the southern end stands a life-sized limestone statue of Priapus, which was relocated in 1938 from the end of the Canal Terrace, where the Pin Mill is now located. Elegant L-shaped flights of steps descend from the southern end to the Croquet Terrace, flanking a Baroque Fountain arranged in a half-well. The fountain is heavily eroded and positioned against the wall, with a rectangular pool in front and rusticated pilasters on either side. The retaining walls of the Rose Terrace rise to about 3.8 meters and terminate with plain pilasters, sweeping around to the west in an arc and stepping down in four stages to a final height of 1.2 meters. These walls feature stone coping supported by shaped corbels and have a shallow plinth.
