Including Retaining Wall And Flagstones, Battery And Mast House, Culzean Castle Estate

The Battery and Mast House at Culzean Castle Estate were designed by Robertson Buchanan in 1815 and Alexander Pollock in 1908. The structure features a double C-plan gun battery with ramparts that include 11 gun ports. On the east side of the battery, there is an octagonal-plan shelter topped with a pyramidal roof and a veranda.

The battery has grassed earthenwork ramparts with embrasures to the northeast and a random rubble retaining wall to the southwest. It includes a vertically boarded timber shelter and flagstone settings for the cannon and shelter, along with nine cast iron cannons. The site is situated on a clifftop, facing the Firth of Clyde to the north.

The Mast House features a veranda supported by octagonal columns with foliated iron brackets, and there are timber seats against the outside walls. It has a vertically boarded timber door on the southwest and a slated roof with timber skirting. A 12-pane timber framed fixed casement window is located on the southeast. Inside, as seen in 2010, there is a single octagonal chamber with vertically boarded timber lined walls and ceiling, a timber floor, and a timber window shutter. The base of a truncated mast is positioned at the center of the chamber.
