The Royal Exhibition Building in Melbourne marks 125 years of history by opening its doors to the public this weekend. Multiple reports say the site is closely linked to several significant national and military uses over its lifetime, including hosting Australia’s first parliament. The building has also been used as a Royal Australian Air Force (RAAF) training facility. During earlier periods, it served practical medical purposes as a temporary hospital. The weekend program is presented as a chance for visitors to explore the building’s past and its varied roles. While the outlets focus on the same historical highlights, they describe the event primarily as an anniversary celebration centered on public access and recognition of the building’s heritage. The coverage indicates that the property’s long-standing place in Australia’s civic history is the focus of the commemorations, with emphasis on key moments including parliament, defence training, and emergency medical use.
