Old Windmill & Observatory
Old Windmill & Observatory Review
This 1824 construction is the oldest remaining convict-built structure in Brisbane, dubbed the "Tower of Torture" by convicts forced to power a treadmill to crush the colony's grain on windless days. When fire razed part of the city in 1864 the windmill survived, later repurposed as an observatory. Stripped of its blades, the tower now resembles a lighthouse.
