Henry Head Battery

Henry Head Battery is a coastal fortification at the northern entrance of Botany Bay near La Perouse. Underground bunkers, tunnels, and gun positions form an intricate network built into the rocky headland.

The battery was built between 1892 and 1895 when Australia wanted to protect its harbors from enemy warships. It was equipped with special guns that could sink below ground level to stay less visible to incoming attacks.

The fortification shows how Australia defended itself against foreign warships coming from the ocean. Visitors can see how soldiers worked here and understand the role this battery played in protecting the coast.

The site is reachable via walking paths from La Perouse and the remains are freely accessible year-round. Dry weather makes exploration easier and safer, and the paths are straightforward to follow.

The ammunition storage rooms have double walls and vaulted ceilings designed to resist direct hits during combat. This heavy construction reveals how seriously the defenders took the threat of attack from the sea.
