Melbourne's Old Parliament House was originally the Federal Parliament House. Built in 1927, it has undergone two expansions and is now the History Museum. It has completed its 61-year mission to the Parliament House. The Capitol is magnificent and beautiful in appearance, typical Victorian style and unique in style. Melbourne's Old Parliament House is a landmark in Australia's political history, where all the debates and decisions of major international and domestic events from 1927 to 1988 were passed. The political democracy of the Commonwealth is also shown here, and the conference rooms and offices are urgently needed to be expanded due to the growing number of MPs and senators, because the demand cannot be met, so the new Parliament House has been built, and it has become a historical museum.
