Description
This former powder magazine for a fog signalling station is a small, single-storey building with a rectangular shape. It features a narrow, grilled door on the gable end that faces away from the sea. The walls are constructed of coursed rubble and have rounded parapets at the gable ends, which include a square step at the apex and quarter-round corbels. The roof is pitched and covered with slate, topped with heavy ridge tiles. The entire building and its surrounding walls are limewashed. Above the door, there is a coat of arms of Trinity House, with '1861' inscribed above and 'MAGAZINE' below. The building is enclosed by low, white-washed rubble walls.
