Brisbane’s oldest building is The Old Windmill in Observatory Park, built by convicts in 1828. The building was originally used to process wheat and corn crops for the Moreton Bay penal settlement, and had a treadmill that could be used when there was no wind, as well as a technique to punish the convicts. Today, the windmill serves as a tourist attraction.

It is difficult to verify the oldest building in Adelaide, but most signs point to Holy Trinity Church, which was constructed in 1838. The church opened in August of that year, within two years of the settlement of Adelaide. Made mostly of bricks, it quickly became a landmark due to its “peaked cap” top tower design and Vulliamy clock. It still operates as a church today.
