(2) Monument comprises the remains of a World War II heavy anti-aircraft gun battery. An irregular area measuring 80m from NE to SW by 55m transversely, consisting of two octagonal concrete gun emplacements incoprporating six ready lockers for ammunition. Between the two gun pits is a rectangular concrete, five-bay magazine for the longer term storage of ammunition, partly buried and surrounded by a blast wall for further protection. There are also two, less robust, gun pits on the Eastern side with some evidence of ammunition lockers in brick and concrete. In the centre of this arrangement lies the concrete command post. The area covered by the original designation did not relate accurately to the remains described in the original scheduling description.
