The Henry Head Battery is an artillery battery located on the northern side of the entrance to Botany Bay at Henry Head, La Perouse, New South Wales, Australia.[1]
Constructed between 1892 - 1895 with 2 BL 6-inch Mk V disappearing guns,[2] the fort operated until 1910, upon which the fort became obsolete.
The battery along with 2 six in gun emplacements and observation posts was re-utilised 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. The doubling up of walls and ceilings was a preventative measure meant to stop the walls from collapsing in the event of a direct hit. The battery is currently not in use.
