1997 Coastal Battery. Two brick and concrete twin 6 pounder emplacements with observation towers, magazines, workshops, engine rooms, searchlight platforms and shelters survive. Early in the First World War the Admiralty decided that the chain of islands in the Forth estuary, Inchcolm (Scottish NMR NT18SE.
- , Inchmickery and Cramond (Scottish NMR NT17NE 71. 00 and 100) should be fortified. In support of the outer line of the submarine net defence, 12 pounder (Naval) Quick Firing (QF) guns were mounted on Inchmickery. The battery was first manned in 1915. In the revised general scheme of the revision of the Forth Defences it was decided to remove these and replace them with four QF 4-inch Mk III guns.
During 1916 and 1917 the guns were transferred from Inch Garvie (Scottish NMR NT17NW 192) and were subsequently removed in 1924. During the Second World War, Inchmickery was armed with two 6 pounders Mk I on Mk I mountings with gun numbers 24 and 25, these being installed between December 1939 and January 1940 respectively. It is not clear when these guns were removed.
There is an inscription by the pier which reads No. 10 Section, 2 Company, C of E (F) , Royal Engineers, 1939 - 1940. ( PRO WO/192/256).
