[[Image:WWIIBunkA-HENRYHEAD0028.JPG|thumb|right|300px|Look out point with a special position for a large gun or cannon to be fired from]] The '''Henry Head Battery''' is found on the La Perouse side of the inlet to Botany Bay near the edge of a cliff that drops down into the ocean on Henry Head, [[La Perouse, New South Wales]], [[Australia]]. <ref>{{cite web|url=https://www.ozatwar.com/bunkers/laperousebattery.htm|title=La Perouse Battery, Sydney, NSW|website=www.ozatwar.com}}</ref> ==History== This fort and bunker building was built in-between 1892 - 1895 with a large [[disappearing gun]] emplacement (a special hole in the ground that the cannon shoots from and then disappears into). The fort was used until 1910, upon which the fort became useless. The fort that had 2 six inch gun emplacements and special lookout positions was reused during [[World War II]] to protect the entrance to Botany Bay.<ref>{{cite web|url=https://www.nswgolfclub.com.au/guests/history.mhtml|title=NSW Golf Club - La Perouse, New South Wales - History|website=www.nswgolfclub.com.au|access-date=2019-02-11|archive-date=2019-02-28|archive-url=https://web.archive.org/web/20190228184352/https://www.nswgolfclub.com.au/guests/history.mhtml|url-status=dead}}</ref> The underground bunker and tunnels inside the fort had vaulted weapons storage rooms with double walls and ceilings. The doubling up of walls and ceilings was a special way of stoppng the walls from collapsing if the fort suffered a direct hit from a missile (rocket) fired from an enemy ship. The battery is currently not in use. <gallery> Image:WWIIBunkA-HENRYHEAD0042.JPG|Disappearing gun emplacement Image:WWIIBunkA-HENRYHEAD0107.JPG|Looking at the back wall of the inside bunker Image:WWIIBunkA-HENRYHEAD0030.JPG|Gun emplacement Image:WWIIBunkA-HENRYHEAD0110.JPG|Inside the underground section of the fort Image:WWIIBunkA-HENRYHEAD0092.JPG|One of the hallways forming part of the underground complex Image:WWIIBunkA-HENRYHEAD0105.JPG|Gun emplacement Image:WWIIBunkA-HENRYHEAD0023.JPG|Gun em
