Battery Observation Post on Rottnest Island


The Battery Observation Post on Signal Ridge was built in 1938 had the code name "The Fork" and the troops referred to it as "Queen Anne's Mansions". There were two other Battery Observation Posts on the island at Bickley Battery. The Battery Observation Post had instrumentation that measured target information which was passed on to the plotting rooms and guns on Rottnest Island and the other batteries in the Fremantle Fortress area. The top floor of the Battery Observation Post was used to direct and observe the guns at the nearby Oliver Hill Battery. The Fire Commander was located in the Fortress Observation Post on the floor below. The nearby lighthouse was occupied by the Royal Australian Navy during WWII.
