Constructed between 1892 - 1895 with 2 BL 6-inch Mk Vdisappearing guns,[2] the fort operated until 1910, after which it became obsolete.
The battery, along with two six-inch (152.4 mm – diameter) gun emplacements and observation posts, was re-employed during World War II to defend the approaches to Botany Bay.[3] During WWII, it was armed with two 18-pounder Mk IV field guns and two QF 3-pounder Hotchkiss guns.[2] The underground bunker and tunnel complex consisted of vaulted ammunition storage rooms with double walls and ceilings, which were designed to stop them collapsing in the event of a direct hit.
The remains of the fortifications can still be seen.
