The Signal Hill Battery was constructed in 1892-3 at Watsons Bay and is adjacent to the Signal Hill Lighthouse on Old South Head Road.
The Battery was one of a set of three coastal defence fortifications in Sydney, New South Wales, Australia, the other two being the Ben Buckler Gun Battery at Bondi, and the Shark Point Battery, Clovelly. Each battery consisted of a gun pit that incorporated a BL 9.2 inch (234 mm) Mk VI breech-loading 'counter bombardment' British Armstrong 'disappearing' gun. The various Australian colonial governments bought nine such guns and an extra barrel before Federation. The Signal Hill gun bore Serial Number 7318 and its barrel survives and was on public display at the Royal Australian Artillery Museum at North Fort, North Head, before the museum closed in 2010.
