Kithill Castle

Kithill Castle is an early 19th-century engine house, originally for the Princess of Wales Mine, converted around 1880 into a spa and health resort by William Dingle, and now a private house. The building is constructed of rendered rubblestone with large granite quoins. A moulded granite string course sits above the ground floor on the front elevation, and a flat plat band is positioned above the first floor. The slate roof features hipped ends extended to the rear in a cat-slide form, with brick stacks to the rear.

The building originally comprised one large room per storey and was initially four storeys with a flat roof. The height was reduced to three storeys in the mid-20th century. A projecting porch on the ground floor is covered in locally made Phoenix terracotta ornamental tiles, topped with a moulded granite cornice and a slightly coved roof. The porch features an entrance door and rectangular side windows with margin glazing bars. The first floor has two round-headed sashes with thin glazing bars, and two further round-headed sashes above with radiating glazing bars and stone keys within the round arches. The right-hand side wall includes 12-pane sashes with segmented arched heads on both the ground and first floors. One second-floor sash has been altered to the bottom light.

A kitchen wing extends to the rear, with a further two-storey extension on the east side. This rear extension is of rubblestone construction with a slate roof and gable ends, incorporating 12-pane sashes on the ground floor and a single 16-pane sash above. Original late 19th-century cast iron grates have been retained within the interior. William Dingle, the patron of the conversion, was an eminent leader of the Wesleyan Church in Callington.
