Napoleonic Fort Guardhouse, Approximately 30 Metres Inside Entrance To Northern Fort

The Napoleonic Fort Guardhouse, located approximately 30 meters inside the entrance to the northern fort in Berry Head Country Park, was built between 1798 and 1802. It was extended at the rear by 1811 and again between 1865 and 1906. The building features roughcast walls with pilasters made of Devonian limestone ashlar and hipped slated roofs, with the late 19th-century roof being higher than that of the original front range.

The guardhouse has a two-room front range, which may have originally included a verandah. It is a single storey and is four windows wide, with a central doorway. Broad pilasters with plain bases are positioned between and flanking the openings, and raised bands just below the eaves serve as substitutes for capitals. There are two matching pilasters on the left side wall and three on the right side wall. The windows are wood-framed, with some likely dating from the 19th century, featuring wood mullions and upright glazing bars.

Inside, the guardhouse has king-post trusses that display carpenter's marks.
