Governor's Observatory

The remains of Governor Brisbane's observatory are located within the Park to the south west of Old Government House near the highest point in the Park. It was constructed privately by Governor Brisbane in 1822 and became government property in 1826 under Governor Darling.

Astronomers at the Observatory included Christian Carl Rumker and James Dunlop. The building fell into a bad state of repair once James Dunlop left his position as Superintendent of the Observatory in 1847 and was subsequently demolished except for the stones still standing in the Park. These are the remains of the original  transit circle telescope stones used inside the observatory domes.
