Description

The terrace walls and two flights of steps located to the south of Morval House are likely from the 17th century but were remodeled in the 19th century. They feature low stone rubble walls topped with 19th-century coping and stepped buttresses that have set-offs on the south, east, and west sides of the raised terrace in front of Morval House. The structure includes retaining walls on the east and south, with corners on the southwest ramped up to a higher terrace wall on the west. There are two flights of steps that connect the lower ground on the east to the higher ground on the west.
