Description
Jackdaws Castle is a roofless rectangular classical temple built around 1740, possibly by Lord Pembroke, located on a berm. Each short side features a recessed center with an arch that has architrave moulding. A moulded impost band runs along the side walls, separating an upper circular panel with keys from a lower niche. At the top, there is a modillion entablature that extends along the long sides. The niche design is mirrored on the long elevations, leading to projecting pilasters that define a colonnade of four columns topped by a pediment. Inside, the ends of the structure are apse-shaped and include niches. The building is constructed of stucco over brickwork, with a stone plain plinth, cills for the niches, and steps leading to the colonnade. The Corinthian columns, which have plain shafts, are made of stone and are said to have originated from the former Devonshire House in Piccadilly, London. Ball finials above the entablature indicate a change in direction and slope.
