Information

This new Bronze plaque marks the exact point where Colonel William Light started his historic survey of Adelaide on 2nd May 1837 and was known as “Trig Station A”.

Colonel Light was the first surveyor in the world to use trigonometrical surveys to fix property boundaries and to lay out the proportions for the future suburbs of the new Colony of South Australia and was far more accurate than using the standard chain survey that was common practice until then.
