Brisbane Open House, October
The windmill on Wickham Terrace, Brisbane, is believed to be the oldest surviving building in Queensland.
Built in 1824 by convicts, they used a treadmill to grind grains until wind-powered sails were installed in 1828.
In 1862, it became the first home of the Queensland Museum! Given how small it is inside, the displays would have been limited.
Since then it has been used as a signal tower and weather observatory. In the 1930s and 1940s, it was host to pioneer television broadcasts.
It has been protected from rainwater damage by cement render since the late 1800s. The render is scored to imitate the stone blocks it covers.
