Description
The perimeter walls of Launceston Castle were built around 1840 and include some medieval fragments. They were constructed for the Duke of Northumberland using slatestone rubble, with dressings made from local greenstone, volcanic stone, and polyphant stone. The walls serve as roadside retaining walls along St Thomas Road, Western Road, and Castle Dyke, featuring some Gothic style elements, likely re-used from the collapsed Watch of Witches Tower during road construction. These high walls have doorways inserted at various intervals and are part of a significant landscaping project initiated in response to concerns about the castle's condition in 1840.
