Summary

Citadel Battery was built in c. 1900 to defend Dover Harbour and was equipped with 9.2 inch guns between 1901 and 1902. Gun emplacement 3 was located at the eastern end of the complex and was one of three . Each emplacement is essentially identical, with only slight variation in the positioning of particular features, construction is of concrete and steel throughout. The battery remained in use thoughout the Second World War but the guns' shields was adapted such that the guns could be traversed 360 degrees. This was so that they could fire in any direction if needed. (location accurate to the nearest 1m based on available information)

Summarised from report:

Three gun emplacements were constructed and armed at the Citadel Battery between 1901 and 1902, these were for 9.2-inch BL mark X guns on barbette mountings. A Report of the Committee on the Armament of Home Ports, dated 1905, severely criticised Citadel Batttery: it considered, first of all, that the 9.2-inch guns did not provide sufficient cover against bombarding cruisers, especially with the position-finding equipment in use. In 1910, the parapet carriages for the machine guns were replaced by tripod mountings, and in December of the same year one of the 9.2-inch guns (no II or B gun) was removed to Woolwich and the emplacement remained empty thereafter. The two 9.2-inch guns and two machine guns remained as mounted armament until 1916, when the machine guns were withdrawn. In 1919, two 6-pdr sub-calibre guns (for practice) were mounted on the 9.2-inch weapons. The three emplacements are arranged in series, each one comprises a gun pit defined by a barbette, 2.2m high, which splays to the rear and joins with parapet walls which run between the emplacements. Each emplacement is essentially identical, with only slight variation in the positioning of particular features. Construction is of concrete and steel throughout. Emplacement for gun no III is virtually a mirror image of emplacement 1. There are minor variations: the two cartridge recesses have brass frames and there are two secondary ready-use lockers, probably for shells, one of which is blocked by earth and rubble. The scar of the 12-carbine rack is visible but similarly obscured. (1)

The battery remained in use thoughout the Second World War but the guns' shields was adapted such that the guns could be traversed 360 degrees. This was so that they could fire in any direction if needed. (2)
